Status: RESOLVED DUPLICATE of bug 404637

(Firefox :: Shell Integration, defect)

Description

[Tom Oldbury]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9) Gecko/2008051202 Firefox/3.0
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.9) Gecko/2008051202 Firefox/3.0

In GNOME on Ubuntu 8.04 Hardy Heron I currently have my antialiasing settings set for subpixel smoothing, to make it less sharp on the eyes. However, Firefox 3.0 does not seem to respect the settings, and the text appears sharper than it should. (See screenshot)

Reproducible: Always

Steps to Reproduce:
1. In Ubuntu Linux, set antialiasing to sub-pixel smoothing (on LCDs only, otherwise it looks ugly)
2. Open a Firefox window, compare Ubuntu menu bar and Firefox menu bar, you can see it's definately much sharper. 
Actual Results:  
Firefox appeared much sharper than the system overall. 

Expected Results:  
It should query GNOME and act appropriately. 

Ubuntu 8.04 Hardy Heron. Firefox 3.0 Release Candidate 1. I currently have Firefox 3.0 beta 5 installed, I am just running this to test it, I have not replaced it or updated any profile, if that matters.

The issue is with Cairo. Firefox uses its own version of Cairo that is different from the one used by GNOME. If you if you use the Firefox 3 version from Ubuntu you shouldn't see this issue.
