Extreme jitter in VR mode

[justinwasilenko]

Another upgrade issue that happened in 0.8.5 and is still persistent in 1.10 and Unity 5.4.

We have a cockpit game (Minos Starfighter) the camera is a child object of the cockpit. While in VR mode the camera has a extremely bad jitter as shown in this video:

When not in VR mode there is no jitter.

Thanks for the bug report. We've heard of this in a few other places. What exact version of Unity are you using? What device are you testing on?

[justinwasilenko]

Sorry for not getting back to you right away. It's happening in Unity 5.4.3p1.

Testing on a Samsung S6 and iPhone 6. Happens in both the editor and in the builds.

By any chance are you "far away" from (0,0,0) ? I have seen similar issues when having transforms with big numbers

[wrh]

@nathanmartz Are you aware of the related/identical issue where relatively fast-moving objects are rendered jittery, with obvious frame drops? I've reported it here and it's been discussed here, but still present in Unity 5.6.0b6, and I suspect it's a deeper issue, more your responsibility than Unity's.

Issue still present in 5.6.0b8, tested on a Pixel. Example project + GIF here
