Description Hugo Rens 2016-07-30 19:30:57 UTC

Use of application dashboard seemingly brings the cowpositor (GLX 3.1 on ATI with catalyst) to crash. A black square appears on the menu icon in the panel and there is no more transparency or whatever.

FTW, panel is **located on top of the screen**, so the menu icon is on the upper-left corner.

Any attempt to restart the compositor (eg killall plasmashell && kstart plasmashell) will fail until every 3rd party apps' icons (telegram, skype, ...) is clicked once.

When the latter is done, the black square disappears and a killall-kstart brings the compositor back to life.

The figure shows in 1) where the black square appears and 2) what to click

Reproducible: Couldn't Reproduce

Steps to Reproduce:
1. Open Applications Dashboard
2. Click an icon
3. Crash ?


Expected Results:  
Open the application dashboard and launch the clicked icon.

This could be a GL problem, probably caused by the driver. The system is an arch linux with the catalyst driver installed, xorg version freezed to 1.6.

It may be important to notice that the bug 362531 (https://bugs.kde.org/show_bug.cgi?id=362531) is also present, I issue killall and kstart at each login.

I'm aware this is certainly a niche problem, and that the bug is unreproducible exept randomly, I just hope this bug will help undertand others.

is plasmashell or kwin crashing?

No, both kwin and plasmashell remain usable.
Only the compositor, as far as I know, crashes. The systemtray and dashboard are buggy but running.

Oh, my bad...
Actually the windows remain usable (draggable, etc...) but there is no more transparency effects (blurry panel, console background...), and this black square on the top of the screen.

I haven't still been able to reproduce this bug, though.

Comment 5 Marco Martin 2016-09-19 14:23:01 UTC

so seems, nothing is crashing, but composite effects gets disabled?
Martin, any idea on that?

Comment 6 Martin Flöser 2016-10-04 05:26:16 UTC

please provide output of
qdbus org.kde.KWin /KWin supportInformation

when the problem happens. Please also provide a screenshot of the problem.

@Hugo Rens is this bug still relevant for you after updates?

Sorry for my lack of feedback, I didn't actually encountered the bug after a few updates (as far as I can remember) and I'm afraid I can't tell you exactly what update solved the issue. So no, the bug isn't relevant for me anymore.

Can I (and should I) do something to close/delete the issue ?

Comment 9 Alexander Mentyu 2018-02-26 21:58:32 UTC

No, thanks for your feedback
