I've got a client which has noticed a little gray box appearing in the corner of buttons on click, on Android 8 when using an app in Xamarin.Forms. Does anyone know if this is just expected behavior or if it's an issue?
Thanks
Check if the behavior matches this bug in Xamarin.Forms
If so, and you do need to set a background color, the only workaround I found is to set a color filter instead of the Control's background color
Control.Background.SetColorFilter(backgroundColor.ToAndroid(), PorterDuff.Mode.SrcIn);
