Why? Wayland not ready?
No. Source 2 still uses some X11 specific stuff and has to be ported over to Wayland before it can work Wayland-native
Most likely - honestly Wayland has been in production for so long that it feels like it will never be ready :(
Star Citizen will release 1.0 before Wayland is ready.
The game would crash on wayland unless you forced it to use X11.
I’m struggling to think of a use case where going through XWayland is preferable over direct Wayland. It’ll just go through Wayland anyway but with extra X11 hacks to convert between the protocols…
What can it possibly fix that running the game under gamescope wouldn’t?
Maybe there are X11 specific calls that aren’t fully supported by Wayland?
Transition takes time
The only way transition works is setting a date to kill something and then killing it.
