Are you saying that at 13px and above the expected font (DejaVu Sans?) is used?

In about:config, if you search for font.name.sans-serif, are all values at their defaults?

Unfortunately, Edit->Preferences->Content->"Default font" hides what is really happening. Use "Advanced" to get a better picture.

But then I didn't expect bug 385263 to change the selected font. I'd be interested to hear exactly how things changed here. What font did you expect and what font did you get before the change?

That sounds the same as the effect of /etc/fonts/conf.d/53-monospace-lcd-filter.conf from fontconfig-config_2.6.0-1ubuntu4_all.deb.

<!-- Use legacy LCD filter on smaller Monospace fonts -->
  <match target="font">
    <test name="family">
      <string>DejaVu Sans Mono</string>
      <string>Bitstream Vera Sans Mono</string>
    </test>
    <test name="pixelsize" compare="less_eq">
      <double>12.0</double>
    </test>

    <edit name="lcd_filter" mode="assign">
      <const>lcdlegacy</const>
    </edit>
    <edit name="hintstyle" mode="assign">
      <const>hintfull</const>
    </edit>
  </match>

I don't know why Ubuntu have chosen to put this after 50-user.conf, and override anything that the user has set.

Does the fontconfig-config package for Ubuntu 8.04 have something similar?
