I’m currently porting a WebVR app to WebXR. I’ve got it mostly working, but my in-game menu system built using BABYLON.GUI.GUI3DManager and BABYLON.GUI.HolographicButton has broken. It works fine before entering WebXR, but the buttons strangely disappear once WebXR starts.
Here’s a playground that reproduces the problem:
The problem arises in both Firefox on Windows (with the WebXR polyfill) and in the Oculus Quest (with WebXR natively, I think).
I never had this problem when using WebVR.
Thanks for your help!
EDIT: Meant to mention that the same thing happens in Chrome macOS when the WebXR device emulator browser extension is installed, in case it helps with debugging. Thanks.
