I recently set up a new Desktop system with an RTX 4080 and installed Fedora Kinoite (specifically ublue-nvidia). Things were weirdly broken in many ways:
- Many apps were flickering between the actual content and black rectangles
- Games didn't work at all, most without any error messages or discernible reasons, some told me they couldn't find a GPU
- I couldn't use CUDA at all
- Firefox couldn't use WebGL or play content with hardware acceleration
After debugging this for multiple days I switched to X11, and everything immediately worked. I'm relatively proficient with Linux, and I have no idea what the issue was or how I could continue debugging it.
So, at least for me, NVidia is still completely broken with Wayland.
It works more or less fine (if you don't care about the feature parity) on bleeding edge Plasma 6 and Hyprland, if you manually apply a bunch of explicit sync patches made by Nvidia a year ago that Wayland devs won't merge.
It works very poorly otherwise, especially XWayland apps and anything 3D - flickering, stuttering, artifacts, out of order frames.
