Created attachment 205164 [details] A simple project based on qt includes flash source. When I set wmode as transparent, flash's background is really transparent. But only bottom compoment is transparent. Both two compoment in flash are assigned as transparent background. This situation also occurrs on Google Chrome when I use original flash plug-in (NPAPI).

Created attachment 209855 [details] Paint current background before pass to flash It seems like flash only paints the front transparent mask. I try to copy the current background to bitmap before flash paints. Then it works, but I'm not sure it might effect the other part or not. Is there any better suggestions to fix this bug?
