White Shadow on Android BlurRadius #15

Closed andre-laskawy closed 3 years ago

andre-laskawy commented 3 years ago

Using the Android Blur Radius, e.g. like this

        <materialFrame:MaterialFrame
            Padding="0"
            AndroidBlurRadius="20"
            MaterialBlurStyle="{DynamicResource DynamicBlurStyle}"
            MaterialTheme="AcrylicBlur" />

and then putting any white control on it (e.g. a White Button) results in a light white shadow around the control, I couldn't find any solution to get rid of the shadow:

Set the AndroidMaterialFrameRenderer.ThrowStopExceptionOnDraw to true

Nice, that worked! Can't debug with this flag on, but I can get around this with a compiler constant.

yup this is a xamarin.android issue, is should be fixed in 16.8 though according to https://github.com/xamarin/xamarin-android/issues/4548
