Details

Hi,

if you have a webpage with a jpg background image and
some PNG image in front, where the PNG image has an alpha 
channel, the color of the background image is slightly
(almost invisible, but still visible) modified even
if the PNG is completed transparent at this position.

Testcase ?
used Build ?

(please always include such informations in a bug report)


Mozilla Version is Mozilla Debian-Package 1.0.0-3

Testcase will be available on http://www.danisch.de in about 24-48 hours.
(See the logo "DANiSCH", you will find a very slight color distortion
in the spanning rectangle.)

regards
Hadmut

bug reports from debian builds are invalid but awe will see if we can reproduce
this.

Please add the URL in the URL field and add a screenshot (via create new
attachment link)
