Still on X11. OBS just works.

I've been using OBS on wayland, they got captures working really well a few years ago.

But for VR stuff I've been going back to X11, and I was just last night trying to finish a screen capture program on wayland (w/ kde plasma) and idk I just have to do repeated screenshots ana analyze those > horrible fps, but at least I think I got that working finally after many attempts last year.

Gaming is not really an issue now with DEs that help ppl disable compositions and wine/proton.
