I actually stopped having problems with steam on Wayland quite some time ago. But, one of the first things I did was turn off scaling (I have 1080 and 1440 screens). There used to be random issues with the menus in steam, and that went away a few months ago.
My only problems (as an NVidia user) with KDE plasma on wayland right now is occasionally discord will just freeze and I need to minimize/maximise to bring it to life. And very very rarely (and actually it might have been fixed, I’ve not seen it in weeks), one screen will entirely freeze and I have to either switch to a console and back or logout/login to bring it back to life. Oh and not a bug, but the OBS issue with global hotkeys. Now I can run it in X mode, but then it will randomly cause an issue where it makes games shudder. Only in X capture mode. It’s most odd.
It brings enough positives compared to X that these really minor problems are worth it.
I have the exact same frozen screen issue!
I thought steam was able to run natively on Wayland?
Worth clarifying from your proton link, it’s still behind an experimental feature flag but the support for Wayland in proton is coming along really well. I’ve just blanket enabled Wayland for all my games and with the latest proton-ge version they all work great.
