Kwin Wayland crashes after sddm login, then recovres but unusable

Running on a hybrid setup (igpu + nvidia gpu), everything was fine until I started restoring some of my settings. I have no idea what is causing this

SDDM Wayland logs are empty

keep in mind nvidia and wayland are no friends especially hybrid-combinations are tricky and often useless with wayland. switch to x11, that’s safe.

to my understanding, wouldn’t the compositor always be on the igpu?

Plasma can be very picky about settings - not limited to - but especially theming can cause weird errors

You just told us - until I started restoring some of my settings

every time I try to mess around with the screen configuration, kwin wayland would crash upon next login
