--- Comment #34 from Mathias Kosch info@mkosch.de 2010-04-26 14:34:00 --- I now spent some time to create an improved version of my patch with the known issues fixed. I didn't yet perform further tests which parameter combinations are effected by the 'special case'. Instead, I restricted the patch to the currently tested parameters (RGB images with 24 or 32 bits).
You can find the recent patch here: http://www.winehq.org/pipermail/wine-patches/2010-April/087789.html
