GearVR Stutters (vibrates) even the eye shape (Video to show it)

Hi there.

I don’t know what is causing it and I don’t know how to solve this, even in an empty scene I see the same effect:

Everything stutters, you can see it even in the per-eye shape, it vibrates as crazy when I rotate the phone… impossible to use anything with this effect, and I don’t see this happening in other apps (not my apps, market apps I mean)

Why is this happening? Any help will be very much appreciated…

Cheers and thanks in advance!
