Can you describe the issues a bit more detailed? (e.g. screenshots?)

[6/15] WineD3D: Replace the position fixup mul-add-add with a MAD

[Chris Robinson]

I think the problem is that the replacement has incorrect order of operations. 
Originally, it was adding the half-pixel fixup then multiplying to invert the 
Y, while the MAD replacement does the Y invert first then the half-pixel fix.
