Sometimes when you move your head around, it will jitter a lot. I have seen this happen on Android and iOS but it could affect other platforms as well.

Steps to Reproduce:
1. Move your head around
2. It might jitter.

Observed Results: The screen jitters

Expected Results: The screen will not jitter

Potential Workaround:
It seems that exiting the game and restarting the game will fix it temporarily.
