no idea if this is a recent development, but stumbled upon the info. you can run wine games on wayland directly, as opposed to the default, running it through Xwayland translation.

what you need to do is clear the DISPLAY variable. I use lutris, so I add it like so:

mangohud reports "wayland", without the line it's "xwayland", so it works. the results for the few games I play are awesome - no resolution issues, no alt-tab glitchings, no launch multiple times before it starts... didn't run any benchmarks as it's already maxed out at 60 fps on Ultra. but so far, very cool!
