borderBottomLeftRadius et. al. produce blurry corners on iOS

[joe-noel-dev]

It seems that when specifying some, but not all of borderBottomLeftRadius, borderBottomRightRadius, borderTopLeftRadius and borderTopRightRadius, you can end up with some strange effects in the other corners.

See this rnplay or code snippet:

'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  View,
} = React;

var SampleApp = React.createClass({
  render: function() {
    return (
      <View style={styles.container}>
        <View style={styles.box} />
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: 'white',
  },
  box: {    
    borderWidth: 1,
    borderColor: 'black',

    width: 150,
    height: 150,

    borderBottomLeftRadius: 10,
  },
});

AppRegistry.registerComponent('SampleApp', () => SampleApp);

react-native 0.28.0

Seems to occur on iOS, but not on Android

Am I doing something wrong, or is this a bug?

Looks like a bug, I actually hit this problem too. I think it only happens on devices with a low screen density.

For me this happens on a real device but doesn't happen on the simulator.

[manicakes]

I can't reproduce this (tried Simulator and a couple real devices).

[janicduplessis]

Seems to only happen on non retina devices, I can reproduce it using the original code sample on an iPod Touch. I can also reproduce the bug by setting the scale of the simulator to 50%.

I tested this, and it only appears when the screen's resolution is too low. Is this significant? I think most device from now on will have high resolution, so this wouldn't be an issue.

for me happen on real device: iphone 6 plus

ps. react-native:0.34.0

[frontendloader]

Merge #10823 and #11897 into this one?

Minimal reproduction on RNPlay: https://rnplay.org/apps/Cl4tGg

Am seeing this as of react-native version 0.40.

happen on react-native 0.42.3 & iphone6 plus
