Bug 413836

Application: systemsettings5 (5.17.2)

Qt Version: 5.13.2
Frameworks Version: 5.63.0
Operating System: Linux 5.3.7-arch1-2-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I had changed the compositor's scale method and went to "All Settings" after saving it. (Afterwards, I opened this setting page and left without changing anything and the application was still crashing.)

- Unusual behavior I noticed:
Flickering on the non-active windows.

- Custom settings of the application:
OpenGL 3.1, Scale method: Smooth

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
