Oh, I managed to not be clear on that, sorry!

No, I can't reproduce the no-clickable issue at all anymore. So for me, this
bug is resolved.

@Mads So the issue still persists with KDE Frameworks 5.37 in your normal setup
(ie. when you don't set it to 2;2 manually)?

and also not if you use context menues to start programs.  It only happens to
me if I click directly no a file and then only for certain programs.  E.g.
dragon player seems to work, vlc does not

To clarify: dolphin does not appear to have this unclickable file area issue
anymore if using:
- kde-frameworks 5.37
- dolphin 17.08.0
- plasma 5.10.0
- Qt 5.9.1
- modesetting ddx
- QT_SCREEN_SCALE_FACTORS="2;2"

There might still be an issue at play, but that might belong to another
bugreport (scaling variable set for non-existing outputs (or vice versa) leads
to high cpu usage on plasmashell process and erroneous scaling on outputs that
are actually connected)

kscreen sets the QT_SCREEN_SCALE_FACTORS to
"QT_SCREEN_SCALE_FACTORS=eDP-1-1=2;DP-1-1=2;HDMI-1-1=2;DP-1-2=2;HDMI-1-2=2;" on
my computer when I have chosen 2 as scaling value. eDP-1 is connected, and
DP-1-2 is connected. xrandr also reports that I have the connections DP-1,
HDMI-1, DP-2, HDMI-2, DP-1-1, but all of them are disconnected.

So, that QT_SCREEN_SCALE_FACTORS mentions some ports that might have existed
some time, but for the time being is not there (e.g. HDMI-1-1 and HDMI-1-2).
Might this be the actual issue? Because if I run dolphin with
QT_SCREEN_SCALE_FACTORS="2;2", things seems to just work... (Qt 5.9.1, kde
frameworks 5.37.0, plasma 5.10.5)

I just tried with Qt 5.9.1 and now the file area is completely inaccessible on

Sorry for spamming the bug report, but I did some more testing - there was a
difference between the computers, because one screen ran with
QT_SCREEN_SCALE_FACTORS 1 on the non-primary monitor and 2 on the
external/primary, and the other (the one showing the bug) ran with
QT_SCREEN_SCALE_FACTORS 2 on both monitors. When I changed to 2 on both
monitors, I see the bug on both systems.

So the bug is still there with Qt 5.7.1/5.9.1 and kde frameworks 5.35.0 (again,
if anything needs rebuilding after upgrading from Qt 5.7.1 to 5.9.1 outside of
kio and dolphin, then please do tell..)

we use the modesetting driver for X if it's relevant.

Hm I did some testing myself now, and I don't get this bug either. On one
computer I have Qt 5.7.1 with KDE frameworks 5.35.0 and dolphin 17.04.2
(everything on Gentoo), and I don't see this bug (with 2x 4k monitors). On
another computer we first tested with Qt 5.7.1 and then afterwards with Qt
5.9.1, kde-frameworks 5.35.0 and dolphin 17.04.2 (also everything on Gentoo and
with 2x 4k monitors), the bug happens everytime, we've yet to manage to click
on a icon in dolphin on the external (primary) monitor yet...

The differences between the computers is that one is an XPS15 9550, the other
is a XPS15 9560, and the 9560 one has a pretty recently built Gentoo system on
it.

Is there a component that needs rebuilding against new Qt other than kio and
dolphin that we haven't rebuilt?

If I understand this correctly, then the patch mentioned here is just a
workaround for an underlying qt issue that has been fixed in qt 5.9.1... So you
might want to wait until it rolls out or get it installed in a way or another

I have ever met Brian's issue when I applied the patch to KDE frameworks<5.35.0
to the packages from Kubuntu-ci. The file area becomes non-clickable when I
drag the Dolphin window into the secondary 4k monitor, even before launching
any app.

Today I upgraded from the Kubuntu-ci repository where the framework 5.35.0 has
already landed, and all the bugs were gone. Thanks very much for the
developers' effort.

I'm not sure I understand the question. For clarity, here's my setup: I'm using
a laptop with an internal 4K display and an external 4K monitor, both of which
have a scaling factor of 2. The external display is set as primary. When I run
dolphin, the default window with my home directory appears on the external
display. I can't select any items in the file view or sidebar, though the
address bar and toolbar remain responsive. If I drag the window so that it is
entirely on the internal display, I can select and open files and directories
as usual. However, when I drag the window back to the external display, I can
no longer select or open items again.

If I'm reading the release notes
(https://www.kde.org/announcements/kde-frameworks-5.35.0.php) correctly, the
fix in #18 is in KDE Frameworks 5.35.0, which is now in Neon User Edition.
However, I'm still having trouble with Dolphin. In fact, it's now worse - the
dolphin window is unresponsive on the second monitor even without having opened
a file via double click.

I have met this issue since several months ago. Currently the bug is still
reproducible on my desktop.

Spec:
Kubuntu 17.04 with Plasma 5.9.4 and Dolphin 16.12.3-0ubuntu2
Two Dell 4K Monitors
Set QT_SCREEN_SCALE_FACTORS=2

On primary screen the dolphin performs fine, however when opening a file on
secondary screen the file area becomes freezed.

--- Comment #15 from Sean V Kelley  ---
Same issue:

OpenSUSE Tumbleweed
dolphin 16.12.3

Laptop: 4K display
Attached Display: 4K display

Using hidpi scaling factor of 2 in KDE

Only able to open a single file using Dolphin on the Attached Display.  Further
attempts to open another file on the Attached Display is blocked.  Only work
around, use context menu each time I open a file OR close Dolphin, relaunch
Dolphin and open file.

However, on the laptop display when attached or not attached to the external 4K
display I can freely open files, multiple.


This is super annoying.

Yup, Qt creates native windows. We do winId() on the DolphinViewContainer which
will apparently causes Qt to create a native window chain up until the first
window it encounters.

When I set WA_DontCreateNativeAncestors I suddenly get a mirror of the
DolphinViewController positioned at 0,0 in the Dolphin window. I can't
reproduce with a minimal test case, though.

Seems embedded widgets are (also) broken in this setup, e.g. System Settings
QML stuff or KMail WebEngineView...

My theory: due to the scaling Qt did not create a native window. But once
KStartupInfo is used the wid is needed, thus a window gets created and that is
stealing the events.

This bug is so absurd. The bug does not happen if I don't pass a window to the
"new KRun" call in DolphinViewContainer.

It passes "this", ie. the DolphinViewContainer widget, which has status bar,
KUrlNavigator as well as the DolphinView (one of the affected QGraphicsViews).
I traced it down in KRun to KStartupInfo. If I remove the
KStartupInfo::sendChange(id, data); call in KRun the bug does not happen.

CC'ing David F (as KRun guru) and Martin G (as KWindowSystem guru) - I have no
idea how this happens. The docs for KStartupInfo say it's the "top level
widget", so perhaps it should be DolphinMainWindow (indeed, if for testing f I
pass KMainWindow::memberList().first()) and not the view container? I don't see
how this could end up keeping mouse events (stuff like "window became
(in)active" arrive fine) from the graphics views?! It even affects the places
sidebar which is *not* in the affects DolphinViewContainer but has its own
afaics.

I can confirm when I run dolphin with QT_SCREEN_SCALE_FACTORS="2;2" but when I
run it with QT_SCREEN_SCALE_FACTORS="2;1" it resizes and re-scales fine when I
move it to the other screen. Very weird.

I'm getting hit by the same bug.
System:
- Debian Stretch (testing)
- KDE Plasma 5.8.2
- dual screen setup (one hidpi, one regular 1920x1200)

Same symptom as described by everybody else: an area within the dolphin window
becomes unresponsive to mouse clicks.  I can still use the cursor keys to
change the currently selected file and open a file by hitting return. But the
window is unresponsive to mouse clicks.

I have the same problem but the cause is different. I simply have to hover the
cursor around a bit and it will randomly stop receiving mouse events. 
When this happens, SOME of the files/folders that are listed will still be able
to receive the events. It seems to be completely random.

Also a usable workaround for me on Neon:

export QT_SCREEN_SCALE_FACTORS= && dolphin %u

Took a closer look at this bug since I'd quite like it fixed.

In KItemListController.cpp around line 529, the function: 

bool KItemListController::mousePressEvent(QGraphicsSceneMouseEvent* event,
const QTransform& transform)

does not seem to be receiving any mouse events when clicking on the left half
of the view after the bug is triggered. Debug output is generated from clicks
in this part of the screen before opening a file, but after opening a file the
debug output is gone.

I'm getting the same thing with current KDE Neon. (Plasma 5.6.1, Frameworks
5.24.0, Dolphin 16.04.2)

On my center monitor, mouse clicks register correctly on the right half of the
Dolphin window but not on the left half.

Exactly the same behaviour here.
The only QT_* variables defined are:

$ set | grep QT_
QT_DEVICE_PIXEL_RATIO=2
QT_IM_MODULE=xim

The issue doesn't happen if I unset QT_DEVICE_PIXEL_RATIO.

Dolphin Version 15.12.3

Using:
KDE Frameworks 5.23.0
Qt 5.6.1 (built against 5.6.0)
The xcb windowing system
