Hi again, this time I encountered a weird behavior with the Advanced Lightning Option. First time I played the game the option was On and I had no problems for a few turns, but that didn't last long and I had to disable it due to glitches encountered afterwards (very blurry screen constantly.

Now the weird part is that I have been playing with the option Off since then and I noticed that sometimes I get glitches like the pictures below with lots of rectangles all over the screen, and this happens after checking Research/Design Units tree buttons. This time though I decided to try turning advanced lighting back On and the screen fixed itself.

Gltich with Advanced Lighting Off:

Now the glitch with advanced lightning back On is gone, except for the portrait:
