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

I went to the compositor settings to re-enable it. After setting the checkbox to off and on again I clicked Apply button, then closed the app using the window close button. A message about app crash appeared.

The crash can be reproduced sometimes.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
