That looks like your camera is losing 1 or more of the sensor inputs - which can be due to light interference, camera angle, hat angle, headset angle (if using track clip) etc.
Go into your camera view, ensure you can see all three points of input etc, and when you move your head, that none of them are going awol. I'm suspecting camera angle due to the fact its when your looking straight ahead.
hope this helps,
