Sentry Crash Report:

Description Lyubomir 2021-05-27 13:52:23 UTC 
Application: systemsettings5 (5.21.4)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.0-17-generic x86_64
Windowing System: Wayland
Drkonqi Version: 5.21.4
Distribution: Ubuntu 21.04

-- Information about the crash:
- What I was doing when the application crashed:
I have just installed a beautiful splash screen and was browsing for some more, then it showed that there were some network problems, smh about host and sockets. The popup with the network error was still open and was above/covering the center part of the "Splash Screen" browser. I clicked on the close button of the inactive "Splash screen" window that was below the popup with the network error. Then the crash happened.
- Unusual behavior I noticed:
There was a network error about hosts and another network error about sockets being displayed consequently while i was browsing the "Splash screens", although i did have internet at that time.

The reporter is unsure if this crash is reproducible.

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

Looks like it's crashing in the gallium graphics drivers. I would recommend reporting upstream.
Comment 2 Lyubomir 2021-07-05 13:15:45 UTC 
Upstream bug for reference: https://gitlab.freedesktop.org/mesa/mesa/-/issues/4902
