Was a jpeg reading problem, not a renderer one. Cairo never has problems with transparency, because it ignores it.

In case it's of any help: I've implemented RGBA bitmap characters, so it's possible to load a PNG with alpha directly in Gnash. This shows a lot of rendering errors, which of course may be caused by a bug in converting PNG data to image rgba (in GnashImagePng.cpp), but are quite likely to do with this bug.

mmm.. cairo seems to be NOT doing it.
Could only check over the dog, as cairo seems to be
having problem with stage resizing (never gets
the white border around).

In the following flash ad:
http://ads2.siol.net/ads/1/Siol_TV_300x250_fantek.swf
some pixels on the borders of the fingers where the background image is bright are rendered cyan. It is easy to on the dog in the background, or on the white background if you launch gnash from command line.
Seems like an integer overflow. The image is rendered properly in the proprietary Flash Player.
