I just updated to 5.11.4 and want to confirm that the crash when closing the
Virtualbox settings dialog does not happen anymore. Thanks for the fix!

Git commit 55f169d1c34491f0d97c8b7a162f4ba60f6849e2 by Martin Flöser, on behalf
of Luboš Luňák.
Committed on 18/05/2017 at 17:30.
Pushed by graesslin into branch 'Plasma/5.8'.

fix occassional crash caused by needlessly delayed signals (bko#363224)

As pointed out by the Valgrind trace in #363224, delaying the signal causes
the EffectWindow* argument to become invalid before the connected slot is
called (this is because Qt discards only delayed signal->slot calls where
the receiver gets deleted meanwhile, not the sender and definitely not
a random argument.
If the supposed glitches really happen, they should get fixed correctly,
and for all cases (I doubt only desktop number would be involved but
not e.g. shaded or minimized states).

Created attachment 104621

proposed fix

As seen in the Valgrind log, this is basically bug #347490. The supposed fix
30e6ae34d7 for that one only moved the problem, so instead of delayed slots
crashing because of deleted Client objects, it now crashes because of deleted
EffectWindow objects.

This patch reverts that commit and also the delayed signals, based on the
following:
- 30e6ae34d7 only papers over the problem
- the commit introducing the delaying of the signal doesn't explain it (*sigh*)
and so the only reasoning for it is a comment in #347490 with a supposition
about it, and I cannot see any glitches with this patch attached (although
admitedly I didn't try too hard, given that I don't know what to look for)
- the logic of delaying of just this one signal seems wrong to me, if it would
be needed, surely other signals would need similar delaying as well
- if it turns out any delaying is actually necessary, it should be done
properly where needed (such as triggering a delayed repaint in the appropriate
place)

As I said before, the crashing only happens if I have the Translucency or
Dialog Parent effects enabled. Now I can confirm that it only crashes if these
effects are enabled AND I'm using the Plastik theme. It doesn't crash when
using Breeze or Oxygen, even with these effects.

Hi all I reported Bug 375256 which is a dupe of the current bug here but was
affecting Google Earth as well. 

I'd like to add some further information in that switching my windows
decoration theme to Breeze has completely stopped the crashes. I was using the
seven black theme from here:

https://store.kde.org/p/1002615

I conducted further testing using the Oxygen windows decoration theme and that
is ok as well however plastik also crashes Kwin.

If it helps any, I can relay that I am using Translucency, but none of the
Dialogue (Base, Parent, etc) effects are enabled.

Again, on amdgpu.ko with a Radeon R9 270.  I will gladly test the patch on my
system; though I run in to this so rarely that I can't reliably reproduce it, I
can still ensure it does not do any further damage either.

My system is always under heavy load because the I/O is crap due to buggy/bad
SATA drivers.  So I cannot comment on whether that causes it or not.

I also found that only "Dialog Parent" and "Translucency" trigger the crash.
"Dialog Parent" is more reliable.  I found that the crash is triggered more
often if the system is under load.  I did a "ninja -j6" build of llvm during
the tests (pegging all CPU cores to 100%) and it seemed to be enough to
reliably trigger the crash.  On an idle system the crash didn't happen so
often.

If all you want is that this bug doesn't bother you. You can just disable
compositing for application related to crash through kwin rules. Sorry for my
bad english.

Progress!

In System Settings, I opened the Desktop Effects menu and disabled everything.
The crashing stopped. I enabled effects one at a time until I found the
offenders. Disabling 'Transparency' and 'Dialog Parent' effects was the
solution. If all other effects are disabled, enabling either of these results
in crashes. I can enable all effects except these two and it won't crash.

Nope. I have an Intel i5-2400 and an Nvidia GTX 960. My CPU is ~5 years old,
but perfectly capable. I can reproduce the issue even with no load on the
CPU/GPU. The VM isn't even running, just Vbox main window and settings menu.

Let me know if I can do anything to help.

openSUSE Tumbleweed or Leap?

I need to setup a VM with the same system. My distro has an older 
virtual box and I don't want to exclude the possibility that the version 
of the software matters.

Thanks a lot for the output. I don't see what I expected but the 
sequence of events is "interesting". I will need some time to properly 
understand what's going on there and compare it to other windows. 
Hopefully I find a clue.

First off, although we already established that, it does not depend on intel
graphics as the crash happens here with an nvidia GPU.

"it only happens on older systems or on systems under stress at that time. The
quite often mentioned VMware and virtual box could verify the stress situation:
resources are passed to the VM and taken away from the main system."

My system is indeed older but the "under stress at that time" is definitely not
true. My system is almost idle, the virtual machine isn't even running and the
crash reliably happens when I close the configuration dialog of virtualbox-qt
5.1.8 (openSUSE, qt 5.7.1).

I ran xev > kwin_crash_xev.txt while triggering the crash; since I don't what's
of interest to you, I'll attach the whole output.

2017-01-22 Thread Martin Gräßlin
https://bugs.kde.org/show_bug.cgi?id=363224

--- Comment #41 from Martin Gräßlin  ---
I'm sharing my theory on what we see from the backtraces we have:

The crash happens when a window is exposed to the window effect system. This is
the part that compositing is required.

The code in question delays a call to the end of current event cycle. And it
looks like the window gets destroyed while the call is being delayed.

This would mean that the crash happens when a window gets opened and closed in
a very short time frame. In fact the window must be closed when KWin gets the
event that the window is created. The destroy event must already be queued.
It's the only explanation I have for the window getting destroyed during the
delay.

Now I tried to verify this assumption with test applications which simulates
this condition. But I failed.

Thus my theory: it only happens on older systems or on systems under stress at
that time. The quite often mentioned VMware and virtual box could verify the
stress situation: resources are passed to the VM and taken away from the main
system.

What I need:
Verification that my theory is correct. Please run xev and trigger the crash.
It should show us whether there was a short lived window.

In addition I will need someone who can test a patch if my theory is correct.
Without being able to reproduce I just cannot write and test a patch. I can
write it, but need someone to test and verify.

I want to help!  What can I provide?

(In reply to marc from comment #38)

Maybe you miss my comment #34:
> OpenGL renderer string: Gallium 0.4 on AMD PITCAIRN

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Curacao PRO [Radeon R7 370 / R9 270/370 OEM]

I am using a R9 270 and amdgpu.ko.  I have not used composition for months
until a few weeks ago to see if Mesa 13.0 finally fixes my OpenGL woes.  It
seems to have fixed most of them, but then I get this error.  So I report it.

I wish to be of more assistance, but I do not know what to provide.  I continue
to use my WINE-based task scheduler, and have pressed F10 hundreds of times
since the crash, and don't have it any more.  It is indeed very random.  I can
say I am using the beautiful plastiK window decorations with Breeze widget
styles.  I know that plastiK has been source of bugs in the past.  But still,
it is the only decoration that I truly enjoy, so I continue to use it.

Maybe that is a difference?

 That configuration matches all my systems. I'm quite certain that the GPU is
irrelevant.

Guys [and girls],


 From what I have gathered so far, this is what happens:
- it appears only with Intel on-chip card [HD graphics]
- it only appears when compositor is enabled [desktop effects]
- it only shows in VirtualBox
- it doesn't matter which rendering method is selected
- the issue does not appear on other DEs

Maybe you will be able to reproduce the issue with similar configuration.
It seems that the issue lies somewhere between QT under kwin and 
graphics subsystem, from what I can see.

I'm sorry that you are not satisfied with our quality. We would love to fix

that many users are affected by it.

The problem is: we developers are not able to reproduce the issue. If we try
the steps outlined in this bug and its many duplicates it just doesn't crash.
There is an important part of the puzzle still missing. Something is different
for our users and for us trying to investigate.

Try using a different windows manager for linux. I have some windows
programs which I ran in wine crash like yours and my only solution was to
use a different windows manager than KDE. It seems as though it has been
the cause of the window manager updating itself and now that it has a few
new libraries, kwin and other programs crash constantly. I am now using
windows managers like enlightenment, awesome and standard gnome windows
managers and I havent gotten a crash since.

[kwin] [Bug 363224] Kwin crashes from time to time (this time using Virtual Machine Manager)

2017-01-09 Thread Martin Gräßlin
https://bugs.kde.org/show_bug.cgi?id=363224

--- Comment #32 from Martin Gräßlin  ---
Adding some information we devs know:

* the crash can only happen with compositing (desktop effects) enabled
* The type of compositor should not matter
* The graphics card should not matter
* the crash is triggered from an event loop hiding the root cause

What we don't know is why it happens. I have never been able to reproduce given
the detailed instructions we have in this report and the many duplicates. This
is a huge problem for further investigation. I have ideas what might be the
cause of the crash, but without being able to reproduce I cannot verify that my
theory is correct and that makes it also difficult to provide a patch.

Given the last point mentioned it might be a timing issue.

OK, some more useful info:

This issue appears ONLY if "Enable 3D acceleration" is enabled on "Virtualbox 
> Display > Display" tab ...

Hope this helps a bit to find the source of this issue. Seems like VBox tries 
to use some kind of 3D accel subsystem and turns it on in a wrong way, or 
whatever.

OK, I can confirm that it only happens with compositing turned "on" - no matter 
which engine is being used [OpenGL 2/3.1/XRender].

Yes, and it seems to be related to either 'APIC' option in VirtualBox, or
Compositing enabled in KWin (doesn't seem to appear if it's disabled) . Need to
do more tests to confirm, if time allows

I just installed Debian testing (64 Bit), selected KDE as desktop and run into

All the backtraces we have currently are lacking debug symbols. Could someone
please upload a backtrace with a backtrace with full debug symbols?

Also could someone still hitting this problem paste the output of:
qdbus org.kde.KWin /KWin supportInformation

Hum?
If you can reptoduce this at will, disable translucency and dialogparent
effects in "kcmshell5 kwineffects", if this "fixes" it, please re-enable either
independently to figure the culprit.

>>> run "kcmshell5 desktop" and disable the indication in the second tab <<<

I've had this already disabled when the crash occured.

Can you create a bachtrace with full debug support (notably values not stripped
- I do not know whether installing the fedora dbg packages would provide that)

Wrt to bug #320536 either a dead engine is accessed or (I rather suspect) QML
doesn't like to be wired down 0x0 objects (in which case we'd need to test the
object and conditionally return QScriptEngine::nullValue()) like so:
