Pins in symbol layer flicker when we zoom out in the map, when zooming in it is fine

[AkshatDubey10]

Environment

• Android OS version: 13, 14
• Devices affected: One Plus Nord CE 2 Lite, Nothing Phone 1, etc.
• Maps SDK Version: 11.8.1

Observed behavior and steps to reproduce

Recently we updated to latest Mapbox Version 11.8.1 from version 10.18.2, in our testing we are facing issue that the pins flicker while zooming out the map, while when zooming in the issue does not happen. This has started happening after updating the Mapbox SDK. I have attached the video for reference.

Expected behavior

The behavior should be that it should not flicker when user is zooming out like in the previous version

Hey @pengdev @kiryldz, could you look into the issue

[pengdev]

Thanks @AkshatDubey10 for the ticket, I've created an internal ticket to investigate, will post updates when we find the root cause. In the mean time, could you share the reproduce steps, how you added these pins? It would be good to provide a minimum reproduce setup.

Hey @pengdev, this is the implementation which works fine on mapbox v10, but breaks on mapbox v11

Hi @pengdev, is there any update on this issue ?
