Steam Deck diagonal dead zone on joysticks

The problem is not with the joysticks, it works fine, I showed it in the video. It’s very uncomfortable to play with such a dead zone, when you literally need to adjust the sight by 1 millimeter, I get an uncontrolled movement to the side.

How long have you been using the Steam Deck? Try adjusting the custom dead zone in Steam settings it could improve your experience. Have you tweaked the joystick settings in the game? Is this issue similar in other games?"
