I discovered, through various tests and play sessions, that a strong enough fan will cause the world to jitter a bit, and similarly affect the controller tracking.

In my Pico4 and Quest 2 headsets, if I was facing a fan the tracking would get jittery all around. It didn’t matter where the fan was in the room (so not a lighting thing), or which fan it is, only that it was blowing hard enough in the tracked area. Playing directly under a ceiling fan on high can do the same thing.

Wondering if it’s just me, if anyone else has noticed something similar, or if someone is willing to test the theory on their own in some “backyard science”.
