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: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Unfortunately the backtrace lacks debug symbols. Please install relevant kwin debug packages and submit a new backtrace with debug symbols.
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!
You need to install debug packages for effects as well.
have not installed debug packages for effects yet, but maybe this helps already?
