with icons, i mean the ones that replace units actual appearance when you zoom out, or on the minimap.

If they are in TGA format, which the ones in BA are, and the sizes (width and height) are non-power-of-two (whihc ome of BA are), then they come out scrambled (like when you unplug the signal cable of old/analog TV sets) on some ATI cards. this is the case for both of my cards, and was reported by many other users, eg for SA44, which uses much more icons.
