same old evil rs485, latest mesa/ddx/drm and linus 2.6.31-rc9 kernel.

if i activate pixel shader in wine, the wow (game) entrance is inverted (upside
down), but correctly rendered. if i deactivate pixel shaders, i get correct
display but some corruption of the rendering.

see image 1 and 2 for inverted and correct (but with rendering errors).

can i use any other test app to check if pixel shaders are reporting inverted
values?

best regards
