I confirm:

• [X] that I haven't found an existing compatibility report for this game.
• [X] that I have checked whether there are updates for my system available.
• [X] that I saw many similar reports about input issues, but none specifically about keyboard input breaking gamepad input until restart.

Symptoms

When I'm running many different games with Proton 10, gamepad is discovered and works without issues, until I touch any keyboard key. Then, no more input from gamepad is being registered until I restart the game.

Downgrading to Proton 9 fixes the issue - keyboard and gamepad input work interchangeably (I can use both at the same time).

I checked with Dualshock 4 and 8bitdo micro.

I tried disabling Steam overlay, Steam Input and Steam Playstation controller support specifically.

I also tried the following commands:

• SDL_GAMECONTROLLER_IGNORE_DEVICES="" %command%
• SDL_JOYSTICK_HIDAPI=0 %command%
• SDL_JOYSTICK_ALLOW_BACKGROUND_EVENTS=1 %command%
• PROTON_USE_SDL=1 %command%

I'm attaching logs from Peglin, but I can add more if needed.
