I submitted this as a bug report last year, as it came in with the Horizons update, but now that the Engineers update is out I think I have my answer. It's not a bug, but a design choice.

And I just think it's awful. I used to love exploring in ED and spending lots of time in the system map but I just can't now. It looks so terrible and unpleasant, very much unlike how it used to look. Planets were only illuminated on one side, toward the star, and it gave a comfortable warmth and consistency to the map. Changing it to add harsh edge on the opposite side of the planets was not only unsightly, it was unnecessary. What did it fix? Who asked for it? Who likes it this way? Anyone?
