After upgrading to f21, I am seeing firefox rendering fonts awfully on many websites.

It looks like the font has been rendered non-anti-aliased, and then scaled by a non-integer ratio.

Examples are facebook and http://www.science20.com/quantum_diaries_survivor.

Comment 1 Ralph Loader 2014-09-14 08:02:04 UTC
fc-match says that 'helvetica' is getting mapping to an old X11 font:

$ fc-match -v helvetica
	file: "/usr/share/fonts/X11/100dpi/helvR08-ISO8859-1.pcf.gz"(w)

Isn't it about time that we just deleted any code path using old X11 fonts when they are not explicitly asked for?

Comment 2 Rick Elrod 2014-10-16 08:29:16 UTC
Seeing this as well...

Restoring my sanity/working around it temporarily by mapping Helvetica to Nimbus Sans L in ~/.config/fontconfig/fonts.conf:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<alias binding="same">
    <family>Nimbus Sans L</family>

Comment 3 Martin Stransky 2015-01-21 14:02:15 UTC
IMHO should be fixed in fontconfig.

Comment 4 Akira TAGOH 2015-01-22 08:06:47 UTC
If we prefer Nimbus Sans L for Helvetica alternatives, it should be fixed in urw-fonts with adding the above config to the package. or adding the following to xorg-x11-fonts-ISO8859-1-100dpi package:


if those fonts are totally useless for applications using fontconfig.
Either way, I expect to see the fix in the package other than fontconfig because it avoids frequent updates of fontconfig for non-binary updates and unnecessary updates for those who don't install the problematic font packages.

I'm not sure how much rejecting X11 fonts affects other applications. reassigning to urw-fonts at this point.

i cannot reproduce this issue on my machine with xorg-x11-fonts-ISO8859-1-100dpi and urw-fonts-2.4-19.fc21 installed.

could you please give more infos how i can reproduce this issue?


Comment 6 Ralph Loader 2015-02-08 05:56:38 UTC
I can no longer reproduce this.  Is this still happening for anyone else?

Comment 7 Ngo Than 2015-02-09 10:44:22 UTC
reporter and me cannot reproduce this issue anymore. I decided to close this bug as "WORKSFORME". Feel free to reopen this again if someone can reproduce it.
