For my Stellar Battle in the Seven Green Hills Zone with the 3D engine, I had to make a point of not drawing anything with a Z less than some (positive) cut off value, determined experimentally. So yes, I found some issues when objects were right up close and friendly.

To speed drawing, I also don't draw anything with ABS(X) < Z. (Y was fixed at 0.) This worked for my chosen zoom factor which gave a roughly 90 degree field of view.
