--- Comment #12 from Mathias Kosch info@mkosch.de 2008-07-27 10:49:39 --- Created an attachment (id=15095) --> (http://bugs.winehq.org/attachment.cgi?id=15095) Screenshot demonstrating the bug
This screenshot demonstrates the problem (for all who want to see). I colored the picture magenta for privacy and bandwidth reasons. As you can see it is shifted upwards.
Unfortunately I didn't yet find time to proceed with the patch development. I would have to run some tests under Wine and Windows to figure out the correct function of "StretchBlt" with DIBs having positive and negative heights. I will proceed when I find some time. As long as this will take you can use my proposed fix. I didn't yet experience any problems with it.
