Endeavour forums helped when I upgraded during the 24 hours when Arch removed Amdgpu firmware. It did kind of make me wonder how many issues like that were present but that I’ve just dodged by random upgrade timing.

Yes of course. What I meant was that yes, it is definitely possible to adjust refresh using kscreen-doctor. But I don’t have any tips on how to do that.

I use mpv-kscreen-doctor and it works to change the refresh rate with mpv on Plasma Wayland.

No idea what it is does behind the scenes though!
