I had problems with the random maps until I started playing with the resolutions. I have bumped my maps up to 2000 x 2000 for any number of provences. Everything is in focus and lines up.

On a Mac Mini but more importantly on a hi res monitor.
Tried the game last night in windowed mode and at a higher resolution and it worked very well. There may be a slight distortion, but nothing that affects gameplay. Thanks for the suggestion.
