Android and BoxView opacity

Hi!

I have a grid containing an image that rowspans the entire grid and a 15% area at the bottom containing a layover boxview with an opacity set to 15% (0.15). This works great in iOS and on Windows Phone.

However, on Android it works in about 90% of the case. In the case that it doesn't work, it renders completely black. If I refresh the view it usually renders OK.

Any idea on what could cause this behavior?
