@freemo for WM I’ve been using Plasma’s Wayland session for way over a year too, I adapted PipeWire early though and had no problems with screenshots or the like, only rare WM crashes and restarts. But these gradually stopped over updates and now I haven’t had a problem for months now, maybe even half a year.
The fact that SDDM still used X and so my system still autostarted it just to display the login manager which would then launch a wayland session was a bit annoying though. Especially since X would often refuse to shut down gracefully alongside the rest of the system and slowed down any reboots by the 1m30s of systemd being patient before shooting it in the head.
