Standalone component to reproduce

import { Camera, MapView } from '@rnmapbox/maps';
import Mapbox from '@rnmapbox/maps';
import React, { useRef } from 'react';
import { Button, Text, StyleSheet, TouchableOpacity, View } from 'react-native';

const styles = StyleSheet.create({
  touchableContainer: { borderColor: 'black', borderWidth: 1.0, width: 60 },
  touchable: {
    backgroundColor: 'blue',
    width: 40,
    height: 40,
    borderRadius: 20,
    alignItems: 'center',
    justifyContent: 'center',
  },
  touchableText: {
    color: 'white',
    fontWeight: 'bold',
  },
  matchParent: { flex: 1 },
});

const AnnotationContent = ({ title }: { title: string }) => (
  <View style={styles.touchableContainer}>
    <Text>{title}</Text>
    <TouchableOpacity style={styles.touchable}>
      <Text style={styles.touchableText}>Btn</Text>
    </TouchableOpacity>
  </View>
);

const BugReportExample = () => {
  const cameraRef = useRef<Mapbox.Camera>(null);

  const onPress = () =>
    cameraRef.current?.setCamera({
      centerCoordinate: [-74.00597, 40.71427],
      padding: {
        paddingTop: 48,
        paddingLeft: 48,
        paddingRight: 48,
        paddingBottom: 480,
      },
      animationMode: 'flyTo',
      animationDuration: 250,
    });

  return (
    <>
      <Button title="Center on marker" onPress={onPress} />
      <MapView style={{ flex: 1 }}>
        <Camera
          ref={cameraRef}
          centerCoordinate={[-74.00597, 40.71427]}
          zoomLevel={14}
        />
        <Mapbox.MarkerView coordinate={[-74.00597, 40.71427]}>
          <AnnotationContent title={'this is a marker view'} />
        </Mapbox.MarkerView>
        <Mapbox.MarkerView coordinate={[-74.001097, 40.71527]}>
          <AnnotationContent title={'this is a marker view'} />
        </Mapbox.MarkerView>
      </MapView>
    </>
  );
};

export default BugReportExample;

Observed behavior and steps to reproduce

https://github.com/user-attachments/assets/a4eb8864-60b3-4e60-8a7a-fda3ed4771c1

After setting camera with a centre coordinate and padding the screen bounds are calculated incorrectly resulting in markers flickering in and out of view.

Expected behavior

Markers remain rendered while still within the screen bounds.

@benjamin-sweney thanks I could repro the issue on maps v11. It seems to be more a padding issue than setCamera:

import { Camera, MapView } from '@rnmapbox/maps';
import Mapbox from '@rnmapbox/maps';
import React, { useRef } from 'react';
import { Button, Text, StyleSheet, TouchableOpacity, View } from 'react-native';

const styles = StyleSheet.create({
  touchableContainer: { borderColor: 'black', borderWidth: 1.0, width: 60 },
  touchable: {
    backgroundColor: 'blue',
    width: 40,
    height: 40,
    borderRadius: 20,
    alignItems: 'center',
    justifyContent: 'center',
  },
  touchableText: {
    color: 'white',
    fontWeight: 'bold',
  },
  matchParent: { flex: 1 },
});

const AnnotationContent = ({ title }) => (
  <View style={styles.touchableContainer}>
    <Text>{title}</Text>
    <TouchableOpacity style={styles.touchable}>
      <Text style={styles.touchableText}>Btn</Text>
    </TouchableOpacity>
  </View>
);

const BugReportExample = () => {
  const cameraRef = useRef(null);

  const onPress = () =>
    cameraRef.current?.setCamera({
      centerCoordinate: [-74.00597, 40.71427],
      padding: {
        paddingTop: 48,
        paddingLeft: 48,
        paddingRight: 48,
        paddingBottom: 480,
      },
      animationMode: 'flyTo',
      animationDuration: 250,
    });

  return (
    <>
      <Button title="Center on marker" onPress={onPress} />
      <MapView style={{ flex: 1 }}>
        <Camera
          ref={cameraRef}
          defaultSettings={{
            centerCoordinate: [-74.00597, 40.71427],
            zoomLevel: 10,
            padding: {
              paddingTop: 48,
              paddingRight: 48,
              paddingBottom: 480,
              paddingLeft: 48,
            },
          }}
        />
        <Mapbox.MarkerView coordinate={[-74.00597, 40.71427]}>
          <AnnotationContent title={'this is a marker view'} />
        </Mapbox.MarkerView>
        <Mapbox.MarkerView coordinate={[-74.001097, 40.71527]}>
          <AnnotationContent title={'this is a marker view'} />
        </Mapbox.MarkerView>
      </MapView>
    </>
  );
};

export default BugReportExample;
