It seems to be related to VRDisplayOculus::SubmitFrame() because it still works well on the screen but glitches in HMD.

What headset has been used to reproduce this? What long is a "short while"?

Comment 3

[Diego Marcos [:dmarcos]]

I cannot reproduce. I left https://aframe.io/examples/showcase/shopping running for 45 mins presenting in VR and everything was working fine when I was back. I was using an HTC Vive. What does glitch mean for you in this context?

I have update my NV driver to 384.94, I can use Oculus Rift to reproduce it frequently at https://aframe.io/a-painter/.

STR:
1. https://aframe.io/a-painter/.
2. Click Enter VR button.
3. Refresh the page.

[Expected result]:
Content presents in the headset.

[Actual result]:
- In the browser, I can see the WebVR content stereo-rendered with proper head tracking. But the images in my Rift is freezed.

I used Oculus rift, the time until the glitches were not constant, however the average was about 7 minutes. The glitches in this case were jerky moves, some freezes and some times the lens were not synchronized, however the browser displayed the images accordingly. I will re-test on beta 12/13 and nightly as soon as possible.

I've reproduced what :daoshengmu is explaining comment 4 once (Vive, Windows 10 and Firefox 55.0b), just after installing Firefox 55.0b. However, after restarting, everything worked fine.

This has likely been fixed with Bug 1394561.  Could you please re-test on the current Nightly build?

I can confirm bug 1394561 fixed this issue. I verified using Fx 57.0b5 and Fx 58.0b1 (build ID: 20171004100049) on Windows 10 x64, on Oculus Rift.
