Camera jumping around when moving head(Oculus Seperate View)

Hello,

I recently updated to the 0.7.0.0 beta Oculus Runtime and the NVIDIA drivers for that SDK.

I have a scene where the user doesn't need any input, it's just an animated camera moving forward. The user can look around while the camera is moving. I used this guide (https://wiki.unrealengine.com/Oculus_Rift_Separate_View) to setup the free look functionality with a moving camera and everything seemed to be working fine.

After upgrading to 0.7.0.0, now when I move my head to look around, sometimes the camera will go nuts and jump around to random angles and positions. It's mostly when looking backwards. This was not happening before I updated to 0.7.0.0, I believe.

Here is a video of the problem (https://www.youtube.com/watch?v=lwpHtWR2P5g)

Is this the Oculus Seperate View causing the problem? Or the tracking camera? Any help would be very much appreciated. Thank you.

    Seems to me you are losing tracking. Are you using DK2 or Crescent Bay?

    Open the console, type 'hmd stats' and keep an eye on 'Vision' and check if it is changed from 'ACQ' to 'LOST'.

    When you lose tracking we switch to head model and unfortunately it is less than ideal (but can't do much about it). With CB / EVT headset (the one that has back of the head tracking) this shouldn't happen too often (or, you need to re-setup the tracker and re-position the player).
