Compatibility Report

  • Name of the game with compatibility issues: The Binding of isaac: Rebirth (with Repetance+)
  • Steam AppID of the game: 250900

System Information

  • GPU: Intel UHD Graphics 620
  • Video driver version: Mesa 26.1.8
  • Full system specs Gist
  • Kernel version: 7.2.7
  • Proton version: 9.0-4 but also affects the latest 11.0-2 or GE11-3

I confirm:

  • [ v] that I haven't found an existing compatibility report for this game.
  • [ v] that I have checked whether there are updates for my system available.

Symptoms

If i add something like SUBSYSTEM=="input", KERNEL=="event*", ATTRS{name}=="*DualSense Wireless Controller Touchpad", ENV{LIBINPUT_IGNORE_DEVICE}="1" to the udev rules so that the Dualsense touchpad isn't treated as a mouse, Isaac sees it as if some button is constantly pressed, SDL and Steam's controller see all buttons behaving as normal. Launching the game with PROTON_ENABLE_HIDRAW=1 fixes it, but I don't see needing to do this as optimal or intended behavior, also after enabling that hidraw option, it seems to have permanently fixed itself, no idea why, even using PROTON_ENABLE_HIDRAW=0 or deleting the prefix
makes it reproducible on my machine.

Reproduction

1- Disable the Dualsense touchpad from acting as a pointer device in libinput (like with an Udev rule)
2-Launch the game with any proton version and steam input disabled (it's not normally needed for this game)
3-Watch the menu behave erratically as if some button is constantly pressed
