Not sure if its XWayland but the vision stutters a lot while everything else is smooth. Also X11 seems unusable for some reason on KDE because I get a lot of glitchy artifacts (and Direct Mode seems to be enabled)
Edit: Using an AMD 6750xt with i5-8600k on Arch Linux with KDE Wayland
Cable only half-way plugged in, if only I had the same problem 😅
In my case it seems to be an unfortunate hardware/software combo bug. I’m due for a new PC sometime soon anyway, I’ll have to be patient for a bit.
