From webvr slack, reported by bartek.  It looks like in the image that we are sort-of in browsing mode, but not fully initialized.

Filing bug to investigate if it affects other devices, webxr as well as webvr, and investigate if the issue still exists.

Hello! With Webvr enabled in chrome://flags when I requestPresent the display.requestAnimationFrame is never called, but instead I get into vr mode with a screen that shows a grid, a window and a controller, like this:

has anyone seen anything like that? there are not meaningful error in dev tools, but in logcat, I can see some issues related to GVR, pasted below:

ok, I solved it :slightly_smiling_face: basically - do not turn on fullscreen manually when entering webvr presentation (I realize webvr takes care of that automatically, but I was still setting fullscreen to on for some backwards compatibility reaons) (edited)
that being said: maybe the api should not silently fail in that case :slightly_smiling_face:


Chrome 67.0.3396.87
Tested on two devices with same results:
1/ Android 8.1.0 on Essential PH-1
2/ Android 7.0.0 on Samsung Galaxy S6


with WebVR flag enabled, but that goes without saying :slightly_smiling_face:
