Symptoms

Controller does not work when Steam input is enabled. For example, any button does not work as "start", menu items cannot be browsed with analog sticks or directional pad and no selections possible.

Turning off (disabling) Steam input makes controller work but input is then in entirely wrong buttons with DualShock 4.
For example, "start" is in right trigger, "confirm" is in square and so on. Browsing menu items works.

Reproduction

1. plug in controller
2. start game
3. try to control with controller

Start by reviewing steam-446040.log and reproducing the three listed steps with Proton 7.0-1, comparing Steam Input enabled and disabled with the DualShock 4. Done means the controller can navigate menus and use the expected buttons in a supported configuration.
