I have done some more tests. The bug is intermittent, it doesn't happens all the times. But once it happens every other video that i load seems to have the same problem. Basically I see the right border of the half dome (watching 180 LR videos) and the "Click to recenter the view" message appears. Skybox VR interface home is not affected by this and the problem wasn't present in previous release (have to say that now I play videos through a smb connection while before i was using a dlna server)
