@gamingonlinux Apparently I'm using a similar setup as you: Fedora KDE, NVidia + Wayland.

I've been using this combination (minus Wayland) since FC6 without any troubles, but lately every update brings new issues.

Are you also experiencing the terrible glitches with the new Big Picture interface? It's usable, but very flickery and jumpy. Also for a while the regular Steam interface hasn't been able to fullscreen any store movies.

Weird, as I believe Steamdeck also runs on Linux/KDE.
