I've been noticing lately that sometimes just sitting in VR the image will suddenly look like it gets bumped. I also need to reset my view fairly often, even though I'm not moving around. I have the two sensors since Touch.
The sensors are in the same locations - I have their spots marked. The direction/angle they face may change a bit, either from me knocking them, or the cats. I wonder if you think that could be causing the bump/tracking issues?
I suppose I could try setting up the sensors/play area again and see of the problem goes away. Or maybe this is something a third sensor will solve. I still only play sit down games.
