repro: enable directx break on warnings in DirectX control panel, then navigate to webvr.info/samples, choose mirroring sample, and start presentation.


May or may not be related to graphical glitches I'm seeing in the webvr samples - the stats display is displaying some garbage characters.  The orbiting cube above the scene was disappearing for some frames, and there were some extra orbitting cubes below the scene.  After investigation, potentially file separate bugs for these issues if they are unrelated.
