After the 1.64 update the deadzone settings for the Xbox One controller axes appear to have no effect. The RT (right trigger) also does not register.
This causes continual input from the Xbox One controller during the session. I use this controller primarily for Eden/Zeus camera and noticed it drifts all the time (stick axes never zero and have no deadzone) and also when trying to assign a keybind the controller always registers an input in addition to whatever key is being pressed.
Tested in Legacy 1.62 and all seems ok there.
