Black canvas on Firefox but not Chrome (errormsg: "Failed to recalculate device parameters.")

I tried to integrate the polyfill + webvr-manager into a project of mine, but I encountered some issues:

I encounter the same problem.
Did you manage to find a solution?

[nylki]

@higain unfortunately not. I wonder wether this might be fixed in the webvr-1.0 branch?

[higain]

@nylki doesn't seem so, also I get the black canvas in chrome and firefox as well.
After updating to three.js version 75 from 68 I need to fix some code, perhaps it fixes itself.

[DigDigDig]

Same for me. Errors on all devices, I still get display on chrome for windows and android. Safari on IOS8 shows until I put it into VRMode.

Does this still happen with the latest changes for WebVR 1.0?

[higain]

No, works fine now. I still get the error message, but it doesn't seem to affect anything.
