[Bug 1674838] Re: kernel BUG at /build/linux-7LGLH_/linux-4.10.0/include/linux/swapops.h:129

2017-04-18 Thread Andrea Bernabei
same bug here, after upgrading to latest Zesty packages as of yesterday.
(kernel 4.10.0-19-generic)

I use firefox-trunk, the nightly build. 
At one point firefox-trunk goes 100% cpu and it can't even be killed.

After a couple of minutes, the whole system freezes.

[Bug 1571513] Re: Please turn off vibrate on touch/typing by default. It makes the phone feel much more laggy

2017-01-16 Thread Andrea Bernabei
Related: the calls to the vibration engine are sync dbus calls. Whenever
the system is overloaded, that will result in long UI stalls. In other
cases, shorter UI freezes can still be experienced.

[Bug 1647982] Re: [Regression]: Krillin gets to a state where OOM starts killing every app (also Dash)

2016-12-09 Thread Andrea Bernabei
I installed: 
libglib2.0-0-dbg 
evolution-data-server-dbg
libc6-dbg

Here are 2 more stacktraces I saved after a reboot.
I'm not sure the problem triggers when the connection starts failing...
internet was working now, but I still had the same problem.

indicator-datetime-service stays at about 4% memory, eds at 6%, for a
few minutes, during which I see spamming of GetObject calls in dbus-
monitor.

At one point then datetime-service starts allocating memory, and slowly
grows until reaching a limit.

Here are 2 stacktraces I saved while datetime-service was allocating memory:
https://pastebin.canonical.com/173275/
https://pastebin.canonical.com/173276/

After a few minutes, gdb reported that 10 thread exited.
At that point datetime-service stopped allocating.

Hope that helps!

2016-12-09 Thread Andrea Bernabei
I confirm I can reliably reproduce the problem. I just have to connect
to WiFi and wait for the ipv6 problem to kick, leaving me connected to
the WiFi AP but without an actual internet connection.

I believe you should be able to reproduce it by creating a fake AP, or
connecting the device to your working AP and then unplugging the modem
from the internet

2016-12-09 Thread Andrea Bernabei
I managed to reproduce the problem by triggering 
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1580146

i.e. I just connect to the WiFi in London's office, after a few minutes
the device stays connected to the AP but cannot actually access the
internet (ipv6 kernel problems, afaik), so calendar sync starts failing.

At that point, I see dbus-monitor being spammed with events, and the
memory taken by indicator-datetime-service increases until settling at
40-50% of the total memory in "ps", once the spamming ends.

zsh
snapd 2.16

--- Description ---
zsh does not seem to load the scripts in /etc/profile.d/ (see 
https://bugzilla.redhat.com/show_bug.cgi?id=88457 ).
As a consequence, /snap/bin is not added to PATH, and running snaps from 
terminal (without snap run) does not work

--- How to reproduce ---
1) Install zsh
2) try running apps provided by snaps from the shell, without using snap run

[Bug 1478319] Re: Wifi doesn't reconnect to AP if it uses the same SSID than another AP

2016-10-26 Thread Andrea Bernabei
@All:

do we actually want this behaviour? Is SSID the only ID we can use to
identify APs of the same "group"?

I was actually hoping we could *stop* connecting to other APs just
because they have the same SSID.

Plenty of routers come preconfigured with the same SSID, see "iPhone" or
"Ubuntu" when you create a hotspot on those devices, or "ASUS" if you
have an Asus router.

Fixing this "bug" means trying to autoconnect to random APs that you
find while walking around the streets.

And when you couple that with bug #615239 you get the followign result:
your phone will stop trying to autoconnect to your real home AP when you
get back home because it is stuck on the password prompt that it
triggered while trying to autoconnect to a random AP you found on your
way home, just because it had the same SSID.

[Bug 1635971] [NEW] WebRTC: meet.jit.si videocall does not work

2016-10-23 Thread Andrea Bernabei
Public bug reported:

krillin, rc-proposed/bq-aquaris.en channel, revision 456

I previously reported bug #1466015 about meet.jit.si not working on 
webbrowser-app, but that bug was marked as duplicate of another bug that is now 
marked as "Fix Released".
But meet.jit.si still does not work.
I'm opening a new bug since the errors in the log are different from the ones I 
reported in the previous bug.

How to reproduce:

2) click on Go to start a new videocall

Expected outcome:
a videocall is started

Actual outcome: 
nothing happens

[Bug 1631447] Re: SlotsLayout padding grouped property needs to assigned member-by-member, can't be assigned as a whole

2016-10-07 Thread Andrea Bernabei
Thanks Marco!
That makes sense, I'll have a look at that next week!

** Summary changed:

- SlotsLayout paddings can't be bound to another layout values
+ SlotsLayout padding grouped property needs to assigned member-by-member, 
can't be assigned as a whole

** Description changed:

+ ubuntu-ui-toolkit/staging branch, r2139
+ 
+ At the moment to assign paddings of a SlotsLayout you can only do:
  SlotsLayout {
-   id: myLayout
-   padding.top: units.gu(15)
-   padding.bottom: units.gu(5)
+   id: myLayout
+   padding.top: units.gu(15)
+   padding.bottom: units.gu(5)
  }
  
+ Assigning the whole padding at once is not possible:
  SlotsLayout {
-   padding: myLayout.padding
+   padding: myLayout.padding
  }
- 
- Would return an error:
+ as that returns an error:
  
  Slots.qml: Invalid property assignment: "padding" is a read-only property
  So to achieve this we need to manually assign the subvalues.
  
  It would be nice to do it all at once.

[Bug 1277030] Re: Scrollbar should match overlay-scrollbar style.

2016-10-07 Thread Andrea Bernabei
Hi Robert, I implemented the new scrollbars a few months ago. 
Can you have a look and confirm if the new scrollbars fix your problems?

(I'm not sure I understand, from the description)

The Scrollbars I implemented are for Qt apps that use the Ubuntu UI
Toolkit

[Bug 1561861] Re: UbuntuColors.Orange should be Ubuntu.orange instead

2016-10-07 Thread Andrea Bernabei
Hi liu-xiao-guo,
I have just sent an MR that fixes the typo you reported.

Sorry if it took so long, I was not aware of this bug (as I'm not in the
SDK team, but I implemented ListItemLayout) and only just found it while
I was doing a random text search for launchpad bugs that were affecting
components I wrote.

Thanks for reporting the bug, it's important to have a polished and
reliable documentation!

[Bug 1630683] [NEW] ListItem: setting implicitHeight has no effect

2016-10-05 Thread Andrea Bernabei
Public bug reported:

ubuntu-ui-toolkit/staging, r2133

Description:
Creating a ListItem and setting its implicitHeight has no effect.
This means any component that derives from ListItem has to be implemented 
setting its height, while the best practice (as far as I know) is that 
components are supposed to set their implicit size, and leave the "real" size 
to the user of those components.

Investigation:
I spent some time on investigating this already. The problem is:
- 
http://bazaar.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-toolkit/staging/view/2133/src/UbuntuToolkit/uclistitem.cpp#L1128
This means every time the width of the parent changes, ListItem will reset its 
implicit height to the default value. As a consequence, specifying a custom 
implicit height value is not allowed, because any parent's width change would 
cause it to be overwritten.
- 
http://bazaar.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-toolkit/staging/view/2133/src/UbuntuToolkit/uclistitem.cpp#L1130
 At this point the item has the implicitHeight set by the testcase below. 
Calling _q_updateSize overwrites what the user set.


Testcase:
import QtQuick 2.4
import Ubuntu.Components 1.3

Item {
width: units.gu(42)
height: units.gu(75)
ListItem {
id: menu
Component.onCompleted: console.log(height, implicitHeight)

//This is overridden on ListItem init and on every parent's width 
change.
//It is as if it weren't there
implicitHeight: 5000

//Explicitly setting height is the only way to resize the component
height: 5000

Rectangle {
anchors.fill: parent
color: "blue"
}
}
}

[Bug 1630167] Re: When SlotsLayout uses a Column as mainSlot and view is resized horizontally an inifinite resize loop starts

2016-10-04 Thread Andrea Bernabei
info for my future self: 
I investigated this bug a few days ago, when Trevinho first reported it 
directly to me.

It turns out the loop is triggered when the view is resized so that the
column gets a *negative* width.

At that point you see columns height going 0 to 5 (which is rectangle's
height) and back to 0, in a loop, and width going -X to 0 to -X again.

[Bug 1628161] Re: SlotsLayout height is not dynamically updated when main paddings change

2016-09-27 Thread Andrea Bernabei
Here is a report of my investigation and my chat with Marco this
afternoon:

The problem is topChanged and bottomChanged are connected to _q_relayout().
The relayout function does the relayout of the element, it doesn't update the 
height of the layout.

They should instead trigger _q_updateSize(), that will call
_q_relayout() after updating the size.

There were already functionality and unit tests in place that ensure
that the height is updated whenever the slot-specific paddings change.

There was a test checking that having the "global" top/bottom padding 
*initialized* to a *custom* value would produce a layout with the correct 
height, but there was no test checking that *changing
* the global padding *after* initialization would update the layout height.

Well spotted, and sorry for the inconvenience, Marco!

Thanks a ton for the fix and the unit test! :)

Hi Emanuele, I asked the developer of Ubuntu Shape, and he said the new

It will still take a few weeks before that is released though, as there
are a lot of pieces involved.

But still, I hope that's good news for you :)

[Bug 1625107] [NEW] Xenial overlay PPA: unity8-desktop-session deps conflict with kubuntu-desktop install deps

2016-09-19 Thread Andrea Bernabei
Public bug reported:

Environment: 
Xenial + Overlay PPA, all packages updated as of 14th Sept 2016

Description:
Team's machine.
It had unity8-desktop-session installed, I tried installing kubuntu-desktop but 
that failed.

1) Installed kubuntu-desktop and that removed unity8-desktop-session (I
did not notice that in the long list of modifications to packages so I
let it go on)

2) Tried getting unity8-desktop-session back and had 2 problems:

a) unity-scope-click depends packagekit ---> packagekit can't be
installed because python3-aptdaemon.pkcompat Conflicts: packagekit --->
I can't remove python3-aptdaemon.pkcompat because "packagekit-tools
Depends: python3-aptdaemon.pkcompat OR packagekit-system-interface OR
packagekit"

b) /usr/share/accounts/services/google-im.service is owned by both kde-
config-telepathy-accounts and accounts-plugin-google which is required
by unity-scope-gdrive

I fixed this by "apt remove unity-scope-gdrive account-plugin-google
kde-telepathy-minimal kde-telepathy" otherwise kubuntu-desktop
installation would not even complete

After fixing b it let me install unity8-desktop-session warning me that
it was uninstalling python3-aptdaemon.pkcompat even though packagekit-
tools depends on it

[Bug 1622577] Re: tst_pagestack_deprecated_toolbar unit test warnings with qt56

2016-09-17 Thread Andrea Bernabei
What I'm seeing here:
- the problem appears when cleanupTestCase() tries to destroy the components
- cleanupTestCase() destroys Tabs
- TabBar is somehow destroyed before its style.
- tabsModel in TabBarStyle becomes null because styledItem becomes null
- isVisible() in TabBarStyle tries  to access tabsModel.count and that triggers 
the error.

Adding 
"if (!tabsModel) return false"
is enough to fix the test, although I'm not sure that's the way we want to go. 
We should investigate why that wasn't needed before Qt5.6 and why, for 
instance, the "selected" property binding (which still relies on 
tabsModel.count) does not fire any error.

2016-09-17 Thread Andrea Bernabei
We were previously misusing mapToItem by not passing x/y parameters
and relying on JS to initialize them to 0.
  
Qt5.6 fixes QTBUG-41686 and requires x/y to be explicitly passed.

2016-09-09 Thread Andrea Bernabei
Additional info:

I built usensord on my laptop using 
"go run -race usensord.go"
and that did not show any race condition after usensord stalled.

I also tried "go run -race test.go" using the code from 
https://golang.org/doc/articles/race_detector.html#Introduction
so I think the race detector setup is working, it's just there isn't any race 
condition in usensord or go-dbus

My laptop has 
go version go1.6.2 linux/amd64

Started from Pat's script and found an easier way to reproduce it (note
the final ampersand, which is the trick):

cat ./bombard.sh 
#!/bin/bash
i=$1
while [ $i -gt 0 ]; do
dbus-send --session --print-reply --type=method_call 
--dest='com.canonical.usensord' /com/canonical/usensord/haptic 
com.canonical.usensord.haptic.Vibrate uint32:100 &
((i--))
done


On my MX4 Arale "./bombard.sh 4" is enough to get usensord stuck

2016-09-08 Thread Andrea Bernabei
I had a quick look at this (I have ZERO Go knowledge though), the code seems to 
hang at http://bazaar.launchpad.net/~go-dbus/go-dbus/v1/view/136/dbus.go#L303
i.e. waiting for a reply on replyChan

gdb showed that all threads had an infinite chain of futexsleep() except
one, that was waiting on epollwait(), and above epollwait() that had a
chain of runtime.netpoll().

Hope that helps

[Bug 1621383] [NEW] ppa:ubuntu-sdk-team/staging breaks update from Qt 5.5.1 to 5.6.1

2016-09-08 Thread Andrea Bernabei
Public bug reported:

Environment:
Xenial 16.04.1 with overlay PPA enabled and the following PPAs 
http://pastebin.ubuntu.com/23149312/

Description:
dist-upgrade suggests removing unity8-desktop-session-mir and plenty of other 
uitk packages to replace them with their -gles counterpart.

See the attached dist-upgrade debug log

Mirv suggested this is happening because the Xenial overlay PPA
currently has 5.6.1 while ppa:ubuntu-sdk-team/staging has a "newer"
version of UITK that requires the older 5.5.1, so instead of upgrading
Qt apt decides to remove some packages and replace them with their -gles
versions (which are not offered by that staging PPA, so those are not
causing issues and can be installed)

[Bug 1620991] Re: Anchoring warnings in Buttons page in UITK Gallery

2016-09-07 Thread Andrea Bernabei
rev2045 changes the order in which Scrollbar anchors to the flickable.
since r2045 it waits for the flickable to be initialized before
anchoring to it.

before:
Scrollbar anchors to flickable. Flickable parent changes, engine says nothing.

now:
Flickable is initialized, its parent changes. Scrollbar waits for flickable to 
be initialized, then anchors to it. QML engine notices that Flickable is not a 
sibling/parent, and warns about failed anchoring

My opinion: 
I think we should double and triplecheck if we really need the flickable parent 
hack, otherwise we should remove it. An alternative could be to try and change 
the scrollbar parent at the same as the flickable parent changes, but I'm not 
sure that's going to prevent the warning from showing, as there should still be 
a moment when Flickable and Scrollbar are anchored but not in a relationship 
that allows anchoring one to the other.

[Bug 1620991] [NEW] Anchoring warnings in Buttons page in UITK Gallery

2016-09-07 Thread Andrea Bernabei
Public bug reported:

ubuntu-ui-toolkit/staging, r2090

1) Build uitk
2) run gallery with ./gallery.sh
3) Open Buttons page

Expected outcome: 
no warnings

Actual outcome:
A few "QML Scrollbar: Cannot anchor to an item that isn't a parent or sibling."

Explanation:
That happens because Scrollbar anchors to the flickable item, but the 
ComboButton code has a hack that changes the parent of the Flickable to 
actually be Flickable's child. As a consequence  Flickable is not a sibling of 
the scrollbar anymore, thus producing the anchor-related warning.

See http://bazaar.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-
toolkit/staging/annotate/2090/src/Ubuntu/Components/1.3/ComboButton.qml#L354

[Bug 1620553] Re: OSK becomes unusable as taps are delayed by 1-2 seconds and vibration doesn't occur any more (although gestures continue to work)

2016-09-07 Thread Andrea Bernabei
I'd think it'd be useful to also add the actual problem, so we can look
it up later when needed. But I don't mind

[Bug 1620553] Re: Haptics engine uses sync dbus calls. Was: "Taps are delayed by 1-2seconds, although gestures are not. Keyboard is thus unusable"

2016-09-06 Thread Andrea Bernabei
@Pat this is a bug I accidentally managed to reproduce, not a constant
behaviour.

I don't have a way to reproduce it yet. We "just" have a to find a way
for the haptics engine dbus call to block, in my case I'm not sure what
made that happen, the dbus call was blocking and then returning NoReply.

I tried killing usensord to reproduce the bug, but that didn't help,
dbus just errored instantly with a blabla was not provided by any
.service files".

2016-09-06 Thread Andrea Bernabei
I "think" I found the culprit.
http://bazaar.launchpad.net/~phablet-team/platform-api/trunk/view/331/src/ubuntu/application/common/application/sensors/service.cpp#L84

It seems the old feedback plugin was async (see
https://code.launchpad.net/~kalikiana/qtubuntu-
sensors/feedback/+merge/183456 with
https://code.launchpad.net/~kalikiana/qtubuntu-
sensors/feedback/+merge/183456/comments/431467 and the reply
https://code.launchpad.net/~kalikiana/qtubuntu-
sensors/feedback/+merge/183456/comments/431975 )

while the new one is using synchronous dbus calls.
http://bazaar.launchpad.net/~phablet-team/platform-api/trunk/view/331/src/ubuntu/application/common/application/sensors/service.cpp#L84

For some reason it seems the dbus service in my case stopped responding
to the requests to enable the vibrator, and that was causing the UI
thread to block waiting on a reply on dbus.

  Description:
  All at once taps have become incredibly delayed, by 1 or 2 secs.
  Gestures still work ok, no delay there.
  Swiping the greeter -> no delay. Tapping numbers to input code on the greeter

  I have no idea why horizontal/vertical swipes would be unaffected, though.
  
  The virtual keyboard is also completely unusable because of the huge
  delay that each tap has.
  
  Also noticed that the vibration is gone, taps don't trigger vibration
  anymore.
  
  Webview also seemed to be unaffected by the delays (although I'm not
  entirely sure, the bug is now gone)
  
  I also restarted unity8 and unity8-dash with Mir input logging enabled. That 
showed that the touch events were being delivered as expected, no delay.

  Restarting lightdm (that forces the restart of unity-system-compositor)

  known to cause more stuttering, but I think they're unlikely to be the

[Bug 1620553] Re: [Krillin] Taps are delayed by 1-2seconds, although gestures are not. Keyboard is thus unusable

2016-09-06 Thread Andrea Bernabei
I think I know that it could be! 
I think it's the vibration handler!

After inputting the passcode in the greeter, unity8 prints the following lines 
*after* the 2 secs delay:
org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes 
include: the remote application did not send a reply, the message bus security 
policy blocked the reply, the reply timeout expired, or the network connection 
was broken.
org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes 
include: the remote application did not send a reply, the message bus security 
policy blocked the reply, the reply timeout expired, or the network connection 
was broken.
org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes 
include: the remote application did not send a reply, the message bus security 
policy blocked the reply, the reply timeout expired, or the network connection 
was broken.
org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes 
include: the remote application did not send a reply, the message bus security 
policy blocked the reply, the reply timeout expired, or the network connection 
was broken.


And as noted in the bug description, one of the sympthoms was that vibration 
stopped working.

I think what happened is that the vibrator handler crashed, and on every
tap that requires vibration the system is waiting some timeout for the
vibrator to reply to the DBus call before timing out.

Those calls are probably synchronous, hence blocking the UI until a
reply is received (do we really have to block the UI to vibrate?). But
since the other end is probably dead, the phone stalls until the NoReply
answer is received, and only then the UI thread gets back in control
again.

[Bug 1616926] Re: Scrollbar thumb shows as hovered after mouse is released outside the thumb

2016-08-26 Thread Andrea Bernabei
New hover area check (part of the linked MR)

For vertical scrollbar:
hovered == (x is inside the TROUGH) && (y is inside the THUMB)

For horizontal scrollbar:
hovered == (x is inside the THUMB) && (y is inside the TROUGH)

This means we're also providing an error margin along the "scrolling"
axis (x for vert scrollbar, y for horiz scrollbar), where it's enough
for the mouse to be inside the trough instead of inside the thumb.

This makes it easier to hover and drag both using mouse and touch, as it
currently provides an additional 3dp of interactive area on each side of
the thumb (thumb's width is 8dp, trough's width is 14dp at the moment)

[Bug 1616868] Re: Scrollbar thumb shows as hovered after touch release

2016-08-26 Thread Andrea Bernabei
Implemented solution: since touch does not fire onEntered, when the user
is dragging using touch the hover logic is not called. Hence we should
not call handleHover in onReleased of the MouseArea because that also
fires when touch is released.

We should instead call it in the Mouse.onReleased
The area handling the interaction with the thumb has 
"Mouse.ignoreSynthesizedEvents: true" so Mouse.onReleased will not fire on 
touch release, just mouse release, which is what we want.

[Bug 1358050] Re: Some icons assume familiarity with other OS

2016-08-26 Thread Andrea Bernabei
Hi Alan, 
we're trying to clear the backlog of unassigned bugs that affect Ubuntu-UX, 
please bear with us as we go through them and try to improve the situation.

The designer working on this has just been assigned to this bug. I'm
sure he will provide more information when he gets to it ;)

Contributions are always very welcome, as far as I can tell :)

[Bug 1616936] [NEW] UITK Gallery: pages pushed on the right panel while RTL is active have the wrong size

2016-08-25 Thread Andrea Bernabei
Public bug reported:

r2079

Description: 
Pushing a page to the right panel while RTL is enabled causes the page to be 
pushed with the wrong size

How to reproduce:
0) switch desktop mode on and make sure you have enough room to trigger the 2 
panel layout in APL (i.e. > 80GU, currently). I tested on the M10 tablet
1) launch UITK gallery
2) click on the thunder icon to enable RTL
3) push a page, e.g. Colours

Expected outcome:
The page is pushed with the correct size to the right panel

Actual outcome:
The page is pushed to the right panel but it seems to be as wide as both the 
panels together instead of just filling the width of the right one.

[Bug 1616926] [NEW] Scrollbar thumb shows as hovered after mouse is released outside the thumb

2016-08-25 Thread Andrea Bernabei
Public bug reported:

ubuntu-ui-toolkit r2079

The fix to bug #1608897 created another issue.

The code that checks if the thumb is being hovered currently only checks
the y position of the input event, an optimization that worked well with
the previous assumption that releasing mouse would always reset the
hover state (but that was causing bug #1608897).

There were, in fact, 2 cases before:
- input device moves away (no pressed buttons) -> onExited is fired -> hover is 
reset
- input device moves away while press-hold is in progress --> onRelease will 
reset hover

Now that the behaviour changed and release does not reset the hover
state, we obviously need to check both x and y position

[Bug 1616868] [NEW] Scrollbar thumb shows as hovered after touch release

2016-08-25 Thread Andrea Bernabei
Public bug reported:

ubuntu-ui-toolkit r2079

The fix to bug #1608897 created another issue.

Since MouseArea does not get the exited() signal on touch release (to be
investigated if that's intended), dragging the thumb with touchscreen
and releasing while the finger is still inside the area of the thumb
will cause the thumb to show as hovered even after release.

[Bug 1616865] [NEW] Windowed mode: hover events in the right edge area are not propagated to the application

2016-08-25 Thread Andrea Bernabei
Public bug reported:

=== Environment ===
current build number: 174
device name: frieza
channel: ubuntu-touch/rc-proposed/bq-aquaris-pd.en
last update: 2016-08-25 11:12:19
version version: 174
version ubuntu: 20160825
version device: 20160809.0
version custom: 20160805--42-20-vivid

=== Unity8 version ===
8.14+15.04.20160819-0ubuntu1

=== Description ===
It seems maximized applications do not receive hover events when the mouse is 
close to the right edge, in an area about 0.5GU wide

=== How to reproduce (one of the many ways) ===
0) Make sure the M10 is in "Desktop mode"
1) Download the UITK gallery from the app store
2) Launch it
3) Maximize the app
4) Open a scrollable page, such as Colours
5) Move the mouse to the right edge to reveal the scrollbar

=== Expected result ===
The scrollbar receives hover events over its whole area

=== Actual result ===
The scrollbar does not receive mouse events in the rightmost area, i.e about 
0.5GU from the right edge. As a consequence, it appears as not being hovered 
even when the mouse is inside the right half of the thumb

=== Cause ===
This is probably caused by the component handling the edge push eating hover 
events.
ltinkl said that the EdgePush component has "hoverEnabled: true". That is 
probably why hover events are not getting propagated down to the app.
Hover events in QtQuick are propagated to parents, not to siblings.
