I also included a patch that removes special treatment for R2_XORPEN with black pen. I don't see such behavior in Windows 2000. I also tested Paintbrush from Windows 3.11 and it has no graphical problems except Pick->Tilt, which is unaffected by this code. It's an old hack that is wrong and unneeded now.
Have you tried on an 8-bit display? That's where the hack is needed, and I see no evidence that this has changed. Besides it shouldn't hurt on more modern displays so I'm not sure why you want to remove it.
