--- Comment #8 from Vincent Povirk madewokherd@gmail.com 2010-03-28 19:16:37 --- It looks like it's drawing an image on an ARGB image, then drawing that ARGB image. This fails because we use gdi32 to draw and it does not use the alpha channel. That used to work (for the wrong reasons), so it may be a regression yet.
