Steam: Controller not working anymore in Forza Horizon 4
So I've been playing Forza Horizon 4 for a while without any issues using a XBox One Controller via Bluetooth. First i used Proton experimental and later Proton GE. Absolutely no problem.
Now however, the controller is not being recognized in game anymore (the on screen buttons show keyboard keys, not gamepad buttons) and I can't use any of the buttons (except the screenshot one). In the Steam menu, the controller test settings, big picture mode etc. it works fine and its recognized normally.
I didn't make any changes (before it happened, now of course it tried a bunch of stuff) but I did upgrade the system normally.
Normally regular mode, but I did try big picture with no luck. I also tried Steam overlay on and off. I will try again though all four possibiltues and read up on the GitHub issue thanks!
Just in case anyone stumbles upon this thread at some point here are my current settings:
The compatibility layer is proton-ge-custom (from AUR)
Steam Input Translation in the Forza Horizon 4 Controller Settings is enabled using the "Official Layout for Forza Horizon 4 - Gamepad"
Regular mode (not big picture mode)
Steam Overlay is enabled
I still have the issue that on some screens it shows the keyboard buttons and not the controller buttons but since the controller works anyway I don't really care (it's just the optics).
