Given the following app(same as reproducer):

Example App

import { useState } from 'react';
import { Pressable, StyleSheet, View } from 'react-native';

function App() {
  const [isToggled, setIsToggled] = useState(false);

  return (
    <View style={styles.container}>
      <Pressable
        onPress={() => setIsToggled(!isToggled)}
        style={{ backgroundColor: 'blue' }}
      >
        <View
          style={{
            width: 50,
            height: 50,
            borderRadius: 25,
            backgroundColor: isToggled ? 'red' : 'transparent',
          }}
        />
      </Pressable>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
});

export default App;

If I press on the blue container, it will switch a state value which toggles the background color from transparent to red. Notice that on Android the red container is square even though border radius is set:

@itsramiel

@itsramiel Thanks for raising this, I was able to reproduce this locally.

@cortinico

Hi @cortinico can you assign this issue to me? I am looking into it

Has anyone found a workaround for this? It seems that forcing re-render by setting a different key based on the state (e.g. <View key={isToggled}) does the trick but we don't want to do that for all buttons.

There's another very hacky workaround: set a white color with 99% transparency.

I can reproduce similar issue on my end. When applying a conditional backgroundColor prop to the dot style, the borderRadius property is not working.

dot: {
        width: 4,
        height: 4,
        borderRadius: 999,
        borderCurve: 'continuous',
},

My temporary solution is to set a base backgroundColor on the dot to match my screen backgroundColor in order to make it seems invisible. With that, applying conditional backgroundColor will display the dot in perfect circle.

Not sure if this behaviour is intentional, but it’d be great if this could be fixed or clarified.

fix(mobile): force remount of nav unread dot on hasUnreads change

fix(android): delete enableAccumulatedUpdatesInRawPropsAndroid and ma…

Update to expo 54 (#5468)

Still reproduces on 0.81.5 (Expo SDK 54, new architecture, Android emulator).

Narrowed on device, 60×60 View with borderRadius: 30, background switched on after mount:

undefined or transparent → colour: square
colour → another colour: round
background and borderRadius changing in the same render: round
background present from mount: round

Two more workarounds besides the key and near-transparent ones mentioned above, both keep the radius without remounting:

overflow: 'hidden' on the View
a border of any width, even borderWidth: 1, borderColor: 'transparent'

Still reproduces on 0.86.3
