XR Composition Layers are invisible when the MetaXR feature group is enabled
I am using Unity's XR Composition Layers to render a canvas (like a floating desktop) on a Meta Quest 3.
The problem I am facing is that the canvas is invisible as soon as the Meta XR Feature Group is enabled.
I am using:
- Unity 6000.1.2f1
- Meta XR Core SDK 77.0.0
- XR Composition Layers 2.0.0
- OpenXR 1.14.3
- URP 17.1.0
- Unity OpenXR Meta (for passthrough) 2.1.1
The composition layers work well as long as the ‘Meta XR’ Feature Group is disabled in the XR Plugin Management settings for OpenXR. As soon as it is checked, without changing anything else, the composition layer is invisible on device.
All my tests on device were done with an actual build, not via Oculus Link, as a build is where is should eventually work.
The same issue was posted here on the Unity Discussions Forum. Unity has confirmed that it is caused by a bug in the Meta SDK package, which appears to be disabling certain layers at runtime, which prevents Unity's code from executing properly on the headsets.
Is this already being looked into? When can an update be expected?
Thank you in advance!

Thank you for looking into this. My apologies for the somewhat late reply, I didn't get notified.
Good to hear you likely found the cause.
If it is still useful, you can download a test repo (1 MB) where the issue can be analyzed using the following URL:

Hi, I'm also experiencing this problem where the XR composition layer is not rendering if the Meta XR feature group is enabled. I'm glad to hear there's a fix incoming. Is there an ETA on the fix, or is there any way to work around the issue in the meantime? Thanks!
In the thread on the same topic in the Unity discussions, it is said that a fix will be part of v79, coming next week.
If so, that would be great!
