Comment (by saste):

 Replying to [comment:4 cehoyos]:
 > I tested with several web-browsers and they all show a white background
 as gimp does, so maybe there is the same bug present in ImageMagick and
 FFmpeg.

 As I explained this is not a bug, as there is no "correct" way to drop the
 alpha channel and preserve information.
