I’m using Firefox 3.6 from the ubuntu-mozilla-daily PPA on Ubuntu lucid amd64. Today, subpixel fonts started displaying poorly in Firefox compared to every other application on the system. They are bordered in distracting red and blue color fringes, which typically result from poor subpixel filtering.

I believe the problem is with the in-source cairo bundled by Firefox. This is fixed for all other applications with Ubuntu’s cairo patch debian/patches/04_lcd_filter (see <https://bugs.freedesktop.org/show_bug.cgi?id=10301>). But ubuntu-mozilla-daily recently started configuring their packages with --disable-system-cairo, leading to this regression.

Reproducible: Always
