Bug 462912

Application: kwin_x11 (5.24.7)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-56-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04.1 LTS
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I have multiple desktop environments such as ubuntu, plasma and ubuntudde. I selected x11 instead of plasma or ubuntu wayland during login as that only the one taking me to ubuntu-dde

- Unusual behavior I noticed:
As soon as I enter password, desktop loading started with wallpaper. And the dock is still not yet loaded. Warning message popped up as "kwin has crashed. It seems that kwin_x11 has crashed in a row. Please select another display manager from below." I can only see one option i.e kwin_x11

- Custom settings of the application:

The crash can be reproduced every time.

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