Bug 418978

Application: kwin_x11 (5.17.5)

Qt Version: 5.14.0
Frameworks Version: 5.65.0
Operating System: Linux 5.3.12-2-default x86_64
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:

I turned my PC on again after returning from sleep and I saw that KWin crashed. Unfortunately, I could not load more debuginfo packages since when I installed them after the crash they were newer versions and GDB could not load them.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
