[mono-android] Image Banding

[Jean-Louis Kroon]

Hi everyone,

Im having an issue with my backgrounds. I get horrible image banding when
setting background images with gradients. When I set the background in my
root layout I do it as follows;

            android:background="@drawable/GradientImage" 

I have also tried setting the background of my root layout in the code
(after removing background from axml);

            Window.SetFormat(Android.Graphics.Format.Rgbx8888);
            Window.AddFlags(Android.Views.WindowManagerFlags.Dither);

            BitmapFactory.Options options = new BitmapFactory.Options();
            options.InPreferredConfig = Bitmap.Config.Argb8888;
            Bitmap gradient = BitmapFactory.DecodeResource(Resources, 
                                              
Resource.Drawable.Background_640,options); 
            sv.SetBackgroundDrawable(new BitmapDrawable(gradient));

This is done in OnCreate and unfortunately does not fix the issue,

Has anyone ever came across this issue? Does anyone now how to fix this.
