If you wait 16 seconds, does it revert to its former settings and bring back the image? Which screen? All screens? How many screens do you have? What GPU hardware are you using? Does it happen on X11 too?

 Which screen? All screens? How many screens do you have?  Only one screen.

Thanks for the info.

Comment 4 kevin 2023-06-02 23:28:25 UTC

I've installed nvidia beta driver 535.43. Current updates are Plasma 5.27.5 Frameworks 5.106.0 Qt 5.15.9 and kernel 6.3.4-1. I can now change the resolution and settings will save it after a few of seconds of a dark screen. 

Looks like this bug has been solved.
