Yeah, I think you're seeing at least two ATI driver bugs. The transparent
cockpit is drawn with a stipple function that's buggy in many ATI drivers.
And the ledit text (toolbar?) is still drawn in the front buffer. The
latest source code in CVS is patched for the toolbar problem on some
radeon cards because it was driving me nuts on one PC. I made it check
for "RADEON 7000" (my card) but I probably should have patched it for any
old "RADEON".
If you had infinite free time you could fetch the code in CVS and
compile it. But why bother, it's just too old.
