Changing Opacity of a Surface without Basemap doesn't update on screen

Hello,

I wanted to ask if I encountered a bug or just did something wrong.

If I define a plain empty Scene, like so:

Scene _scene = new Scene();

 and I put it into a SceneView, then it renders a gridded gray ball. If I then make a button with action like:

private void Button_Click(object sender, RoutedEventArgs e)
{
	MySceneView.Scene.BaseSurface.Opacity = 0.1;
}

and click the button,  the opacity won't change. If I move the camera then the opacity changes.

This behaviour is weird because if the Scene has a Basemap, then it changes right when I click the button.

Is this intended? And what is a good walk-around of this? I found when I change some other property, like:

private void Button_Click(object sender, RoutedEventArgs e)
{
 MySceneView.Scene.BaseSurface.Opacity = 0.1;
 MySceneView.Scene.BaseSurface.BackgroundGrid.IsVisible = !baseSurface.BackgroundGrid.IsVisible;
}

then it works even when the Scene doesn't have the basemap. But maybe there is a more elegant solution?
