--- Comment #12 from Damjan Jovanovic <damjan.jov at gmail.com> ---
There is a real bug here. FillRect() calls PatBlt(), passing it a negative
width/height in the case of this app, and PatBlt() draws rectangles with
negative width/height shifted 1 pixel too far right/down:

           Wine

Patch with test sent: https://source.winehq.org/patches/data/195952

The testcase draws correctly with this patch.
