I tried plasma-wayland on Arch a couple days ago.
Log in, open firefox. Minimize the window, and the entire machine freezes. This is on an AMD GPU as well.
Every time I try Wayland, whether it be sway on my laptop or plasma on my desktop, I run into snags that did not exist in X. So back to X I go.
I'll switch to Wayland when it's ready "for real, actually, promise", and not a moment before. Maybe when Debian Stable switches to it by default.
