I just setup wayland a couple months ago, so everything should be pretty recent, and couldn't ever get screen sharing to work. It's discord electron, which I think is having some weird interaction with xwayland, but I only researched it for a bit before deciding it wasn't worth it.

Games though can be a nightmare, a recent nvidia driver seems to have created stuttering across all games using X to varying degrees. (downgrading the driver fixes the issue)
