Changes between Initial Version and Version 1 of Ticket #15846, comment 2

initial	v1
1	1	I tried the same test with Quest 3 and Quest 2 headsets using the Meta Quest Link app, USB cables to the headsets, and SteamVR. Both Quest headsets had the boundaries created using the Oculus software by tracing the outline with the hand controller in the same way. The coordinate systems seen in VR were completely different rotated about 100 degrees relative to one another and offset in the room rectangle xy by about a meter along each axis. Furthermore when I set down the Quest 3 for a few minutes and then put it back on it showed coordinate axes with a different orientation and center (about 30 degrees and 2 meters different). That change happened even while ChimeraX was continuously running. So it appears the Quest 3 can change coordinate systems each time it wakes from sleep.

	3	I only saw the Quest 3 change coordinates when waking from a short sleep (a few minutes), the Quest 2 always stayed the same. I saw 3 different coordinate systems for the Quest 3 during different wakes and one of them was identical to the Quest 2 coordinate system. Which coordinate system it choose could be related to what direction the headset is facing when you first put it on.
