map sizing issue?

I searched the forum, didnt find anything related.

Hoping this is a simply reply for someone who knows, but..

When zooming on a map, I tend to have lines disappear. Is there any way to avoid this? Lines are disappearing that should still be on the map, and arent being cut off from the zoom at all. Tried using some different map optimizations, but nothing seems to clear it up.

Thanks!
