Baldur's Gate 3

I use primarily 8bitdo controllers (in xbox emulation mode, so they show up as xbox controllers), and so far I've ran into several major bugs; wondering if others have experienced the same (i.e. it's something wrong with my setup) or found any workarounds

1. The controllers show up as 2 controllers when steam input is turned on -- to workaround this, I need to go into Steam's controller settings and turn off "Steam Input for XBox controllers", and they show up as one again.

2. It seems to have controllers working, they need to be connected before the game starts.

3. When loading a game with 2 controllers connected to the same computer, if you go into the session manager to move characters around (hit start -> LB I think), your first player's screen disappears forever and is unusable.

4. When a controller disconnects, you have to restart the entire game to reconnect them -- I can't figure out how to rejoin if a controller goes to sleep.

Edit: forgot to mention this is on (stock) steam deck. Turns out the problem was Proton Experimental, it works a lot better when I turn off "Force use of specific compatibility version".
