Symptoms

Dualshock 4 issues. The camera strafes around indefinitely, every other input (cross, square, etc) seems to be working

Reproduction

Connect the Dualshock 4
Activate DS4 steam controller support
Launch the game
Load/start a new game
Observe

Start by reviewing the Proton issue report and reproducing the DualShock 4 behavior with Steam controller support enabled for Nights of Azure 2. Compare the camera's continuous strafing with the other inputs that work; done means identifying and correcting the compatibility problem, then confirming the listed reproduction steps no longer trigger it.
