Application: kwin_x11 (5.15.2)

Qt Version: 5.12.1
Frameworks Version: 5.56.0
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: I clicked on the telegram system tray (latte dock) button, this switched the virtual desktop and crashed KWin, KWin automaticly restarted after.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KWin (kwin_x11), signal: Aborted
