Environment

1. react-native -v: 0.47.1
2. node -v: v6.9.4
3. npm -v: 5.3.0
4. yarn --version: v0.27.5

Then, specify:

• Target Platform: android : 5.0/ 6.0 /7.0

• Development Operating System: macOS

• Build tools: buildToolsVersion : 25.0.2

Steps to Reproduce

1. create ListView/ScrollView
2. render each Image item with borderRadius(props or style)
3. build in android 5.0/6.0/7.0 , and android 6.0/7.0 render correct, only android 5.0 render incorrect

Expected Behavior

• android 6.0/7.0 render correct as below

Actual Behavior

android 5.0 render incorrect as below

• If I cancel borderRadius in android 5.0 then it render correct as below

So it seem like the picture will render incorrect(black circle) when use borderRadius with image in FlatList/ScrollView on android 5.0
