I asked yesterday on discord and found out it is a feature of Bazzite. It has a package installed by default called joystickwake. That package is like caffeine but works when a controller is plugged in where it keeps the screen awake. I knew it wasn’t a stick drift issue as I installed some new sticks and calibrated them (the new Gullikit TMR replacement sticks) and even checked again to make sure it wasn’t a button registering as being pressed. In any case, I now have all 3 problems solved.
