SteamInput seems to be hijacking the dualsense even with SteamInput disabled. It is very rare but it tends to happen when you access the quick menu and enable/disable bluetooth devices. The dualsense is connected over USB in this scenario.

would we be able to get a toggle to disable lightbar color assignment by Steam Input? it doesn't seem to work, tends to glitch out.

Steps for reproducing this issue:

  1. Make sure dualsense is connected over USB
  2. Disable steam input for a Dualsense compatible game, such as stellar blade or Silent Hill 2
  3. Mid game open quick settings and interact with the menus, the game will still capture input but this is expected
  4. If everything goes as expected, eventually the lightbar on the gamepad will change to the colors assigned by SteamOS, and the gamepad will now be registered with SteamInput, and we can no longer play the game. Disconnecting and reconnecting the dualsense has no effect, steam input will still hijack the dualsense

I do not have logs available

this seems to be worse in the latest steam stable, i can no longer play stellar blade with HD haptics in game mode, steam input seems to be in a state where it's disabled, but also enabled, letting me open the steamos menu with the playstation button, but i cannot interact with the game

i am on SteamOS main because of the HDR bug reported in 2513 on the SteamOS repo

edit the issue seems to have been caused by proton-GE 11-3, i am not sure what version i was using in my original issue
