Since updating to 0.7, I'm getting an odd problem with Unity builds of my own updated projects - a jagged, flicker that comes on intermittently and seems worse when the environment is darker.
It seems to only happen (so far) when I run builds that have been made with the Oculus Utilities package imported, if I just use the unmodified native VR support in Unity it doesn't seem to occur.
It doesn't happen in other demos (by other people).
OK - so disabling aero seems to have fixed it - was googling the wrong thing. At least now I know what 'black tearing' is, having seen it crop up a lot without really knowing.
