Hi! Does it happen with the sample applications or on a real device? Please insert the code as a highlighted Markdown block next time.

Thank you for the report! I'll check that on my Google Pixel 3a.

Hi. It could be a surface clearing issue. Can you try setting an opaque background on the SceneView?

The sample-model-viewer application works fine on the latest main branch in my case:

I have the same issue while rendering a ModelNode on SceneView. I tried white background on SceneView but couldn't see the model at all.
