Summary: Command and Conquer Generals (Zero Hour) non-buildable
                    items show as black and white rather than greyscale

          Platform: PC
        OS/Version: Linux

This one is a bit odd (sorry, couldn't think of a way to cut down the summary
and still have it include the key bits). Basically the unbuildable buildings
should show up as a greyscale version of the picture in the build menu, but
instead they look black and white instead (as if put through a high quality
photo-copier).

Look at the greyed out icons on the botton right of this screenshot as to what
it should look like:
