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

SSIA, I was messing with rendering backend setting, changing the OpenGL version, and I got systemsettings crash.

The backtrace seems to me the same as in bug 434384, however a comment suggests to file a new report if it crashes under different circumstances, so here it is ...

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Nastavení systému (systemsettings5), signal: Segmentation fault
