Screen freezes after some time

Question

After some time of testing a project in Unreal with the DK2, the screen output freezes (game continues to run, evident by the fact that when disabling stereo rendering the game returns to normal).

And after that the editor crashes when trying to run in stereo again. The only way short of restarting the computer to fix this is to restart the Oculus service (can't run any other Rift application either).

I am running Win8.1 x64 with a gtx970 with driver version 350.12, oculus runtime version 0.6.0.1 (reverted to these after getting the advice from the unreal forums according to the oculus runtime release notes)

Currently running on UE 4.8.2.

This may be fixed in the Oculus branch of UE4. Would you mind trying that and seeing if it solves your issue?https://github.com/Oculus-VR/UnrealEngine

Will do this (will take a bit though) and report back. Thank you!
