Getting freeze at the immersive mode in http://moonrider.xyz

[daoshengmu]

Configuration

Firefox Reality version: FxR 7
Firefox Reality build ID: 485355c

Hardware:
Oculus Quest

Steps to Reproduce

1. Visit http://moonrider.xyz using the Oculus Browser on Quest
2. Click to enter VR (glasses icon in bottom right corner) and press Begin UI.
3. Go to Punch mode, and select a music to start.

Current Behavior

Once punching a block, the screen buffer will be freeze.

Expected Behavior

I checked it works properly in Oculus Browser, so we should be no problem with it.

Error Logs and Stack Traces

I would guess it would be related to gamepad haptic feedback or SurfaceTexture.

We don't use EGLTextures, it's most likely the unhandled error.

We should still be able to exit immersive mode which seems to break when the page does.

[daoshengmu]

Alright, the right fixes is here, #2198. Waiting for the haptic feedback support.

[bluemarvin]

The page crashing should not block us from exiting immersive mode. We should fix that first.

It looks odd. const bool menuPressed = (controllerState.inputState.Buttons & ovrButton_Enter) != 0 is always false after the page crashing.

[bluemarvin]

I think we are trying to exit but something is blocking it. When I pause with the oculus home button I see the spinner for the preview.

[daoshengmu]

We are blocking by the VR immersive state [1]. It looks like OVR needs to call vrapi_SubmitFrame2 to end this frame's state, otherwise, we can't get new button states.

Is this Oculus only or does the same thing happen on HTC?

Unfortunately, they don't support Focus+ controllers, they didn't handle any actions from the controllers.

[daoshengmu]

Focus+ doesn't have this problem. Checked via https://mortimergoro.github.io/webvr_long_pause/.

Reopening until #2198 lands

Resolved by #2198.
