Empty canvas element after exiting VR

[De-Panther]

Configuration

Wolvic version: 1.3 (versionCode 70)
Wolvic build ID: dc05067 (AC 7 5.0.22)

Hardware: Oculus Quest 1. OS 49.

Steps to Reproduce

1. Enter https://immersive-web.github.io/webxr-samples/controller-state.html
2. Enter VR.
3. Exit VR.

Current Behavior

Instead of displaying the 3D scene in the canvas, it displays white.

Expected Behavior

The 3D scene should be displayed in the canvas.

Possible Solution

Context

I'm implementing WebXR Export option in Unity, and it affects experiences and demos using this extension.
Demo: https://de-panther.github.io/unity-webxr-export/Build/
In the case of the demo, with the bug, after exiting VR. it display the background of the canvas which is very dark gray. It should display the demo scene.
Users should be able to interact with the experience both in XR and flat modes.

Thanks for the report! I have observed that indeed in some experiences. We'll take a look.

The issue is seems legit. I managed to reproduce it in Wolvic 1.3.1 and 1.3.2.

The issue is not reproducible in the Meta browser.

This can be somehow related to #604, although I'm not exactly sure.
