Status: RESOLVED DUPLICATE of bug 239701

(Firefox :: Shell Integration, defect)

Description

[Bob]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Some images are systematically displayed with black and white lines and zones,
often like "shadows" of the real image, shifted left or right (or both).
Does not happen with the same version of FireFox (1.0.4) under Windows and Linux.
Happens with .gif and .png images at least.
System is Mac OS X 10.3.
Unable to reproduce on other machines (I have no access to another machine under
Mac OS X), but other browsers display them well, and the downloaded image seen
from another program is displayed properly.

Reproducible: Always

Steps to Reproduce:
Look at images in some web sites like :
http://www.trolltech.com (.png) (icons on the upper right)
http://fr.i1.yimg.com/us.yimg.com/i/fr/nt/ma/ma_mail_1.gif
http://yelims.free.fr/Coucou/Coucou20.gif
Actual Results:  
Images have lines on them.

Expected Results:  
The images should have been displayed without any lines.
