Fullbody glitches in passthrough #104
Description
Hi, I have recently started encountering issues in our application which uses full body tracking.
Bodies are glitching like crazy, until the point of getting stuck into the floor and not moving with the user at all.
At the start of the application there is an onboarding scene in passthrough, and to my surprise, after comparing our scene with the working sample scene you provide, the glitch seems to be introduced only when the passthrough is enabled.
I found out through another issue reported here, that IOBT mode is disabled when passthrough is enabled. I understand that, but I don't think it's enough to explain what I'm running into. What I experience is a completely broken full body tracking in passthrough, not just a lower fidelity mode. It is quite unusable. And I know for a fact it didn't use to be this way, since we showcased our prototype back in December and had it running for hours with no issues at all.
So I am wondering, if it's possible that something has changed with a recent system update? I am a bit lost in identifying the cause of this issue.
I was able to reproduce the glitch in the sample scene provided by you:
while the issue is persistent in all kinds of poses, it is faster and easier to come by it when you sit in a specific position (with your palms pointing up and your arm rotated outwards). The full body tracking seems to struggle to give this pose a proper shape in general, but the difference is clear in these videos:
With passthrough:

glitch makes the tracking unusable. Not captured in this video, but eventually after some time the body will get stuck into the floor and stay that way unless restarted.
Without passthrough:

remains stable for 10 minutes or more, no issues whatsoever.
I'm curious if you have any ideas on this
Thanks!
