Freezing Screen without Head Movement (vorpx and steamvr)

[vargablood]

Description of issue

if i watch a movie or play games where my head is really not moving the picture freezes as long as i start to move again. I found the text quoted below in the vorpx Forum thats maybe helpful sorting out the problem, my screen its not black it just freezes at the last picture. If i disable the osvr server or unplug the usb cable it doesnt stop. But i cant look around ;)

"To avoid potential screen burn-in, vorpX uses SteamVR’s IVRSystem::GetTrackedDeviceActivityLevel function to determine whether the headset is used or not and makes the screen black if this function returns anything else than k_EDeviceActivityLevel_UserInteraction."

Steps to reproduce the problem

Start a game or Video Playback with vortex and dont move youre head.
