320738 - Firefox no longer renders fonts according to fontconfig setup.

Status: RESOLVED DUPLICATE of bug 443308

(Core Graveyard :: GFX: Gtk, defect)

Description

[Philippe]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051202 Fedora/1.5-0.fc4 Firefox/1.5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8) Gecko/20051202 Fedora/1.5-0.fc4 Firefox/1.5

I have tweaked my fontconfig setup so that only fonts of a given size get antialiased. That provides Firefox on Linux a font rendering that's pretty much the same I am getting on a Windows system. To my surprise, font rendering changed completely when I upgraded to 1.5. Firefox does not respect rules I defined in my ~/.font.conf.

Since Firefox uses gtk and has a taste of Gnome, it didn't take long before I realize Firefox font rendering is controlled by gnome-font-properties program. I have yet to understand why though, as this program only provides a subset of the functionality I am getting with fontconfig. In short, the decision to link Firefox to gnome-font-properties is quite questionable. 

This bug may be the same as 307711.

Reproducible: Always

Dupe of 243227.  Been a problem ever since bug 197037 got fixed.

Does this bug occur in a recent trunk build?
