The attached patch seems to fix it, but I don't really understand why. It seems to me that a fully transparent pixel is a fully transparent pixel, and it shouldn't matter what's in the RGB channels. Nor does the application seem to do anything weird to draw it.
And I can't think of an easy way to generate a test image for this.
Dmitry, you sent a gdiplus change earlier that preserved the RGB channels when converting from ARGB -> RGB. Any thoughts on this?
