The appearance of "spidery lines" in map backgrounds is a well known
issue encountered by those running the IDV on machines with AMD video
cards.  Please check out the FAQ on this issue in the IDV User's Guide
either online on built-in to the IDV.

Here is how to navigate to the appropriate FAQ in the online IDV
documentation:

            5.3. The maps appear as a spider web of lines. What's wrong?

Cheers,
