When the Oculus "Health and Safety Warning" is displayed in the HMD, ovr_SubmitFrame fails. This is expected behavior, as the warning is an interstitial that takes over the display until dismissed by the user. A side effect is that ovr_SubmitFrame does not block and throttle the framerate as it would in normal operation. This results in a very extreme framerate for WebVR sites that are rendering simple scenes on high-end hardware. This may cause cooling fans to kick in or battery life to be depleted when not necessary. I would suggest that we add an artificial delay before the next VRDisplay.requestAnimationFrame when ovr_SubmitFrame does not succeed.
