Application: kwin_x11 (5.15.2) Qt Version: 5.12.1 Frameworks Version: 5.55.0 Operating System: Linux 5.0.0-arch1-1-ARCH x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: This crash occurs when I suspend my PC and then turn it back on. - Unusual behavior I noticed: Certain textures appear garbled after the computer is turned back on, most notably the lock screen background and the names of files on the desktop. This may or may not be related to the crash. - Other information of note: My graphics card is a GTX 970, and I use the Nvidia proprietary driver distributed in the Arch "extra" repository as "nvidia". The package version I have installed is currently 418.43-5, but this bug has been affecting me since I installed the OS, and the package has been upgraded several times in that time. The crash can be reproduced every time. -- Backtrace: Application: KWin (kwin_x11), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

Unfortunately the backtrace is lacking debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace.
(In reply to Martin Flöser from comment #1) > Unfortunately the backtrace is lacking debug symbols. If you are able to > reproduce please install debug packages and attach a new backtrace. All right. The crash isn't as reproducible as I thought. Instead of a "KWin has crashed" dialog, I'm just getting a notification from it saying "Desktop effects were restarted due to a graphics reset". I've installed debug symbols, and I'll upload a new backtrace the next time I get a crash. The visual glitches I described are still happening, even without a crash.
Created attachment 118750 [details] new backtrace with more informative debug information All right, here's a new backtrace. The graphical glitches didn't happen this time, strangely enough.
It doesn't seem like it was possible for me to change the status and add an attachment at the same time.
