I want to apologize in advance if this has already been discussed, but I couldn't search for this topic because I don't know the name of the effect, but here goes....
I have noticed that in certain star systems I am unable to see my ships when I zoom into a planet. It was most noticable when the sky was green. I could see the structures and defenses, but my ships were not backlit, or highlited, or whatever, as I zoomed in. This made it extremely difficult to micromanage a battle

Anyway, sorry to post something that you guys have probably talked about at length!
