I wanted to help you a bit with project by sharing some information about other project that aims to run applications from different distros (including gui ones) in userspace with containers, the distrobox.
I installed arch, steam in it (with separated home from my own), installed duck game and launched it through proton 7. It worked pretty well. All input inside game (including overlay), including even gamepad worked.
That said, steam client by itself couldn't receive any input in it's gui apart from copy-pasting, even with uinput module loaded (i did unload it prior to launching duck game).
So i hope this will give you some ideas how to improve this image
