alt Hacker Newsin my mind unfortunately this basically destroys KDE's viability as a gaming platform. SO many older games just do not work properly unless run under X11 (hell, some newer ones too). XWayland is good for everyday applications but for games in my experience it too often falls flat.

You can try running in gamescope, although in my experience Wayland has not been an issue. The few games I have that gave me problems in Wine didn't work any better when using an X11 session.
I was under the impression that the Steam Deck runs under KDE Wayland? I wasn't aware of it having video game support challenges due to Wayland.
I'm very surprised to hear that. Ive seen some issues with apps using Xwayland, mostly scaling related. I dont recall ever seeing an issue with a game running on Xwayland. Its also how the Steam Deck runs all games.
can you give examples of games not working?
what about emulation / virtual machines?
SteamOS, and majority of the big gaming Linux distros like CachyOS and Bazzite default to wayland
Can you give examples?
funny you say that, given that the SteamDeck (the largest/most popular Linux-based gaming console) runs on KDE on Wayland.....
I can't say I've run into issues running games under XWayland, but I have only been using the Wayland session for a couple of weeks now. The blocker for me was Discord (you wouldn't get messages on your phone if you were afk because the idle detection didn't work in Wayland), but the devs there seem to have finally fixed it.
As someone who likes games from various periods (from Ultima IV to WH40K: Rogue Trader), I haven't ran into many games which do work on X11 and don't work on Wayland. Though I don't really have any of the old Loki games (I believe there was a port of Unreal Tournament?), so I might be missing out on the specific games which really lean into certain X11 features which XWayland doesn't support well.
