I think I have the latest drivers. I have a GeForce 6600, but don't remember this happening before I upgraded to it, so I think it might be a texturing problem. If I can "refresh" the texture, it updates correctly. An example would be refreshing the texture on a wings3d Model, or alt-tabbing out of game then going back in.
This happens to all textures, not just the map. Units hardly suffer from the problem though.
I'm alright with this for testing because I don't feel like wasting 2 mins tabbing in and out. But in actual games, seeing those damn lines the whole time gets annoying, and the first 2 mins I spend doing that could be my last
