this works for me in linux arch hyprland DE. First i use this tutorial as a startup: https://www.protondb.com/app/420530#CERtvRb5SE, then i add a rule in my hyprland.conf: windowrulev2 = float,class:^(?i)steam$ (this makes that every time you open steams, its enters in XWayland mode). then i add this launch option: SDL_VIDEODRIVER=x11 %command%, this just makes the game open in x11 enviroment.

pd: i have like 2 or 3 min in game, so idk this covers every aspect of the game, if u want to play the game in fullscreen, this works for me:

Resize windows

binde = $mainMod+Shift, Right, resizeactive, 30 0 binde = $mainMod+Shift, Left, resizeactive, -30 0 binde = $mainMod+Shift, Up, resizeactive, 0 -30 binde = $mainMod+Shift, Down, resizeactive, 0 30 With this binds u can resize the game as you wish, no fullscreen but works pretty well.

Maybe in the future i make another report, i don''t see any solution for arch with DE hyprland. Hope this works for you.

hope you have a great day
