What graphics card and driver do you use?  This is important.  I use a
Radeon 9200 and DRI.  In Warcraft III+opengl under wine,  things would
"disappear", but then re-appear under different conditions. I have
screen shots I can upload that shows this in action.  I used to use an
nvidia card with the official driver.  Comparatively, the nvidia
graphics setup rendered everything perfectly.

You are correct, it used to work.  I just tried it yesterday and it
didn't work for me either.

Unfortunately I can't try your game at the moment cause it will take
me too long to download -- 2 KB/s down only =(
