Desktop moving?

Hummm is that normal the virtual destop move after i calibrated it?? Right or left!!

I noticed something similar in LiveViewRift…How much do you find it moves?
if its a little bit over time it may be yaw drift…other people may have a better idea if there is a method to help with that.

After 5 minutes i calibrated the desk is more to the left or right,i get off the pimax google and im not in the center of my screen. Anyway it weird!!

Humm ok in the virtual desktop settting we have a reset orientation that bring back at your center!! Anyway it boring to reset each minutes!!
