<View style={{
// if `borderRadius` > 0 and `height` is large enough like 3000 (2000 is ok on my android device), `backgroundColor` will disappear.
borderRadius: 1,
height: 3000,
backgroundColor: 'red',
alignItems: 'center',
justifyContent: 'center'
}}>
<Text>Test</Text>

Research direction
Start with the index.android.js reproduction and run react-native run-android on a physical Android device, since the issue does not reproduce on an AVD. Trace the Android View rendering path for a large height, borderRadius, and backgroundColor. Done means the red background remains visible while scrolling on the affected device and the existing reproduction behaves as expected.
