wine-1.2-rc3, Ati 4850, fglrx binary driver
with deleted .wine i used winecfg to set audio to alsa and set virtual desktop
1024x768

demo seems to draw everything correctly, but it flashes terribly all the time.
on the beginning it looks like flashing of black screen, later it flashes with
images from previous effects

when i set registry to use backbuffer instead of fbo flashing remained and also
rendering wasn't correct
