Meta Quest Browser Bug - 3D Scene Jitter - Developer - THREE.js

We are reporting a bug and seeking help. It is most likely a bug of Meta Quest Browser or related infrastructures.

we are developers making 3D VR browser based Apps. We open our 3D Scenes (rendered by THREE.js) in Meta Quest Brower.

The issue is, we notice that the scene would jitter even for the simplest example link from THREE.js official website. To reproduce, just open the following link in Meta Quest Browser and use controllers to drag the scene to rotate.

https://threejs.org/examples/#webgl_animation_keyframes

Jitter will likely to show up (not every time but pretty frequent).

We believe this is more likely to be a bug of quest/browser other than the web page because the web page is simple and good in every other desktop/mobile browsers.

One hint is, the jitter seem only happen (or much more frequent) when Passthrough mode is turned off. If you can not reproduce please refer to this video - it's captured by phone directly into the quest lens.:

This issue currently impacts our app badly - if anyone knows anything please let us know.

Appreciate so much!!
