New steam beta update makes the controller worse while using "Steam input", i was playing Euro truck and Helldivers 2 with Gyro mouse controls + keyboard buttons bind on my controller just fine last week, for some reason it acts like there's 2 controllers with different button presses, for example "A" button turns into "B" button after a few minutes.

to fix this i have to remove the beta update and use the normal client.

this problem is on Steam Linux while playing games with Proton.
