Description Michael Glockenstein 2019-10-12 17:11:08 UTC
Application: kwin_x11 (5.16.5)

Qt Version: 5.13.1
Frameworks Version: 5.62.0
Operating System: Linux 4.15.0-65-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
this happens since some months, not every wake up but very often.
since two or three weeks I have also problems when suspending.
monitors will be suspended but cpu is still running.
after wakeup and re-suspening it works most of the time,
until it crashes again.
I did count yet, but I think every third suspend fails.
I did not changed hardware before the problems arised.

The crash can be reproduced sometimes.

-- Backtrace:

Comment 1 Vlad Zahorodnii 2019-10-14 09:07:06 UTC
Unfortunately the backtrace lacks debug symbols. Please install relevant kwin debug packages and submit a new backtrace with debug symbols.
Comment 2 Michael Glockenstein 2019-10-15 17:15:25 UTC
Yesterday freezing was not possible anymore, so I had to reboot the system, but afterwards the output module of the compositor page switched to XRender. I do not remember if it was OpenGL 3.1 or 2.0 before. I also I have to switch back some notification settings of the KDE plasma workspace, so maybe I need some time to reproduce this again.
For now I have installed kwin-common-dbgsym and kwin-x11-dbgsym. Give some advice please if you think there should be more packages installed. thanks!
Comment 3 Vlad Zahorodnii 2019-10-16 08:06:35 UTC
You need to install debug packages for effects as well.
Comment 4 Michael Glockenstein 2019-10-16 23:38:35 UTC
have not installed debug packages for effects yet, but maybe this helps already?
