Steam Controller flickering between mouse and controller

[racercowan]

Last June I played through the base game just fine, but I just came back to doe EotE, and for some reason touching the right touch pad on the steam controller causes the game to flicker back and forth between controller and M+KB controls. If I'm just moving the camera it makes it a bit rough, but if I'm walking or pressing a button at the same time the camera becomes jerky as it constantly stops and stutters, making flight basically impossible. In menus, the button prompts will flash in or out of existence. This happens regardless of what setting the controller is on, as either a mouse or joystick input it still makes the game bounce back and forth.

Has anyone else had this issue or know how to fix it? It seems different than the other controller issues I've heard of, is there some issue with steam controllers in general right now or do I need to email support to figure out what's happening?

Full disclosure: I have no idea. That out of the way:
That sounds like the controller is sending a mouse emulation signal, so the game is detecting mouse input, switching to M+KB then detecting a controller input and switching back? Maybe?
Have you tried unplugging your Mouse and Keyboard to see if the problem occurs with them disconnected?

A very quick Google search led me to these two threads (about a similar issue with other controllers) and each has at least one suggested solution:
