I used Wayland for a couple years on AMD hardware and it was fine; I didn't really have any issues. Since acquiring a laptop with an Nvidia card as a gift about a year agi (it was a hand-me-down), I switched to X11 because it is still more stable for Nvidia. I will be switching back to Wayland (with Nvidia) when Fedora 40 releases. Hopefully the support for explicit sync patch will be available by that time, but if not I won't be heavily affected, as I am not playing games currently. I expect that patch to fix the black frame insertion during VRR that people have been complaining about, at which point Nvidia will be viable (for me) on Wayland.

I've been on the Wayland train for quite some time now, it's only really had issues with Nvidia because Nvidia refuses to adapt their graphics driver for it. We have to rely on the Wayland and XWayland projects to fix the incompatibilities that Nvidia is too lazy to fix themselves (like not supporting implicit sync). Luckily AMD is on top of things and has worked very well with Wayland for years now, so those with AMD hardware are better off.

EDIT: Here's a link to a Lemmy post about the explicit sync patch. Looks like Nvidia drivers plan to support it in the May 15th patch, so about a month after Fedora 40 releases.
