Application: kwin_x11 (5.14.4)

Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.19.12-zen1-1-zen x86_64
Distribution (Platform): Archlinux Packages

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

I usually put the system in suspend when I don't use it. After resuming, KWin sometimes crashes and restarts seamlessly. The only indication that KWin crashed is the crash reporter notification.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
