It works. Thanks, man! A visual example of the problem and your solution is at http://pastebin.com/0JJQVYe8 . Just curious, how bad is the performance penalty for this double conversion step? Would it be better to have a BLEND_ADD_PREMULT blit mode instead, i.e. put the premultiplication in the blitting code? Kind regards, Florian
