    window-actor: Paint screencast background with white
    
    The buffer rectangle contains the window shadow, but because
    the shadow itself is half transparent, it looks like there's
    a back border around the screencast.
    
    Painting it to solid white makes the window shadow visible
    and the stream looks better.
