Flicker of CircleLayer and 3D Model when tilting/rotating camera (Mapbox Android SDK 11.17.0)

[AuraSdrogo]

Environment

• Android OS version: 15
• Devices affected: Nothing Phone 2 (also Xiaomi MI 9T on Android 10)
• Maps SDK Version: com.mapbox.maps:android:11.7.0

Observed behavior and steps to reproduce

When the camera is pitched/tilted or moved quickly the on-screen circle and a 3D glb model briefly flicker. This is reproducible with this code:

Expected behavior

That flicker should not happen.

Notes / preliminary analysis

It looks like the flicker happens when "loaded: false":

12-11 18:36:40.826 341 341 D MapDebug: SourceDataLoaded: [sourceId: composite, type: Tile, loaded: false, tileId: [z: 12, x: 2148, y: 1465], dataId: , timeInterval: [begin: Thu Dec 11 18:36:40 GMT+01:00 2025, end: Thu Dec 11 18:36:40 GMT+01:00 2025]]

I have no idea why this happens. If this could help, I also tried with rnmapbox in react native and the same behaviour happens. Thank you for your time.
