We need to determine if this problem happens due to a bug in the content or if changes in the browser is necessary.

If it can be reproduced, we should find a minimal test case.  Emunitests should help identify any similar regressions.

Is this with Oculus or Vive?

I am using Oculus Rift, and it looks like very similar to this, https://bugzilla.mozilla.org/show_bug.cgi?id=1383106#c4

Both. However on Oculus this issue is frequently encountered. I will retest it as soon as possible on Nightly and beta 12/13 and try to provide more info.

I'm not able to reproduce this specific bug with Vive, Windows 10 and Firefox 55.0b. However, I've reproduced bug 1383106 once (but only once).

I re-tested using Fx 55.0b13. The reproducible rate has fallen to 10% on Oculus, however now the experience has notable latency.

The remaining hangs and latency issues may have been fixed by Bug 1394561, which has landed in Nightly.  Please re-test on the latest Nightly and let me know if there are still any issues, thanks!
