Steps to reproduce:

Hi!
I am using Firefox Nightly v58.0a1 on Mac, the build from yesterday (2017-10-03) was perfect but today build (2017-10-04) brings back huge memory leaks and flashed in the VR headset (HTC Vive) when going into VR mode.


Actual results:

Redflashes making webVR unusable again.. :( and poor frame rates..


Expected results:

No redflashes and normal 90fps.

Thanks for reporting this, I'll be investigating further to narrow it down.

Perhaps there's a chance it is the same regression reported in Bug 1405950.

Now that Bug 1405950 has landed and fixed the WebGL performance regression, could you please re-test and let me know if it's still happening?

Nightly 59 is still affected by this issue making webVR unusable on Mac.
The left eye is affected by glitches where the image is distorted for a few frames every second. 
Red flashes still appear on the right eye.

As for performances, I have experienced some system crashes due to memory leaks, eating all the ram from my machine and eventually making it crash.

Let me know if I can do anything else.
Thank you

Thanks for confirming, @etiennekingdom.  We will continue investigating from here.

The release notes for the recently updated OpenVR version, 1.0.11, mention that we should update to eliminate a memory leak on osx:
https://github.com/ValveSoftware/openvr/releases/tag/v1.0.11

This may be partially responsible.

I have added bug 1423731 to track the update to OpenVR 1.0.11.

I detected a possible memory leak in accessing Gamepad pose data: https://bugzilla.mozilla.org/show_bug.cgi?id=1424588

Additional discovery:

When using WebVR with a headset, some background processes keep running even after quitting Nightly and taking all of my cpu power for no apparent reason.
(Can be seen in the Activity Monitor)
