I am having this as an on going issue, too, and can't seem to find much information on it. I am using a NVIDA GeForce 980GT and keep my drivers up to date... still, after 1.9 I have all sorts of shadow issues where everything has a black out effect until zoomed way in, and even then the shadows are just, off. Its really frustrating, can't even see my ships in the color scheme I tend to use...
