If you add StackLayout containing a ListView containing BoxView with opacity set to less than 1 it renders opaque every third item.
If you remove the outer StackLayout it renders fine every time.
The attached sample solution provides the error out of the box. Just run the Android Project and every third BoxView will be completely black. All other boxes will be set to 30% opacity.
Look at MainView.Xaml and remove the outer StackLayout to produce the expected behaviour of BoxView.
The Xaml works in iOS and WP so the issue is on Android.

Steps I followed:
1. Open attached sample application in VS.
2. Set android as start-up project.
3. Build and deploy it on emulator, scroll the view.
