Just to confirm so far.
- The stylus is plugged in adjacent to the power port.
- Natural light has been eliminated as a possible culprit.
- ZSpace Control Panel diagnostic tests don’t exhibit the same periodic tracking loss.
As you’ve described things, the fault would seem to lie with the Unity plugin. Given that Unity is our most used engine, and yet we’re not familiar with it causing such issues, my current inclination is to seek further confirmation that the fault doesn’t lie elsewhere.
See the link here for a bare-bones sample built from our Native SDK.

I would be most appreciative if you would verify that this sample also does not exhibit the behavior.
