I wanted to try out KDE on Wayland, but upon logging in it immediately causes a GPU hang. It recovers after a few seconds and I get to use the desktop for anywhere between another few seconds to several minutes, then the next GPU hang inevitably hits. It repeats like that.
The device is a Dell XPS 13 9310, so Intel graphics. plasma packages are version 5.23.3-1, wayland is 1.19.0-2. The kernel is 5.15.2-2-MANJARO.

I’ve disabled i915.enable_psr and enabled i915.enable_fbc as per recommendations in the Arch wiki page for the 9310, and I feel like it improved a bit but it’s hard to quantify. I have not tried other environments such as GNOME or Sway. This is with a newly-created user with default settings, and the session was started with the ly display manager.
Is there anything I could do or is the combination of KDE, Wayland and Intel just not working well?
