Application: systemsettings5 (5.19.5)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-28-lowlatency x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

-- Information about the crash:
- What I was doing when the application crashed:
I 'was in System Settings,
- Custom settings of the application:
I was working on the configuration of the windows and suddenly the error appeared and the composite mode was activated.I was working on the configuration in Desktop Behavior in Desktop Effects and I got the error saying that Kwin will restart it or report the Bug.The appearance of Kwin scratches are very frequent in this KDE Plasma oprerative system, I like its interface but these errors do not let you work normally.

The crash can be reproduced every time.

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