Description

Mapbox Implementation

Mapbox

11.4.1 and up to 11.9.0

React Native Version

0.76.5

Platform

iOS

@rnmapbox/maps version

10.1.33

Standalone component to reproduce
Observed behavior and steps to reproduce

I am running into this issue where I have a bunch of MarkerViews (roughly 20-30). As soon as I render these, I'm unable to pan or zoom the map anymore. It would work at some points, but mostly won't work on the map

I don't know if it is related to hit boxes or anything else, but if I zoom out to a different location where I don't have markers anymore, then it works.

Is there any way I can debug and publish more report on whats going on?

And it works perfectly fine on Android, but not on iOS

I can try to recreate this for the demo, but I fear it might not be reproducible.

react-native": "^0.76.5",
"expo": "~52.0.20",
"@rnmapbox/maps": "^10.1.33",

app.config

RNMapboxMapsVersion: "11.9.0"
Expected behavior

Panning and Zooming Gestures should work

Notes / preliminary analysis
  1. Works fine on Android but not on iOS
  2. If I render null inside MarkerView then it works fine
  3. Doesn't matter what is inside MarkerView (Text/View etc and not does its width/height)

Research direction

No source file, test, or entry point is named. First reproduce the issue on iOS with roughly 20–30 MarkerViews using the listed React Native, Expo, @rnmapbox/maps, and Mapbox versions, then compare gesture behavior with MarkerView rendering disabled. Done means panning and zooming work reliably while the markers are present, with a reproducible case or narrowed cause documented.
