hrm, both the bind mount and script for fixing controllers in waydroid are probably not running in waydroid-launcher. or at least, they're not running for me in gamescope session. i'll have to investigate tomorrow.
i remember KF1 giving me issues on Linux when i switched over years ago but i ended up changing settings or using either the linux port / proton and it worked
as for arma gold idk tbh idk what hardware you're on or what but that should be fine considering how old it is. but it's also an arma game so it's probably CPU intensive. would research it i guess idk
