wine users - Jan 2009 - Why does Guild Wars keep flashing and displaying horizontal bars after it is launched

Hi, I recently installed WINE on my computer. I checked if Guild Wars is
compatible with WINE and it said it would work flawlessly. I installed Guild
Wars through WINE then ran the game. When I launched the game all you can see is
a deformed version of the game with horizontal bars flashing everywhere. I even
installed my graphics card through the Hardware Drivers section in Ubuntu.Does
anyone know what could the problem be or the correct procedure to install Guild
Wars and run it? If it helps, my graphics card is a ATI Mobility Radeon X600 and
in the Hardware Drivers section it's apparently called ATI/AMD proprietary
FGLRX graphics driver. By the way, this game worked perfectly in Windows XP for
me. [Question]
