Anti-aliasing changed after update (or something...)

  • 772

The anti-aliasing of my system (of GTK?) has gone weird after I did one of two things - do a system update, and install gimp 2.7 beta. See images:

Here's the current rendering comparison between Chromium, Firefox and Opera (in that order):

Does anyone know how I can get the old anti-aliasing back? As far as I can tell, I never did anything special to achieve that before. It has always been on the default settings since I installed Lucid few months ago.

Update: I have tried different settings (even though I knew they were already at the "best" settings) in appearance > fonts ( > details) but, as expected, any change there only makes things worse.

Update 2: One/some of these packages are to blame I'm sure:

libc-bin (2.11.1-0ubuntu7.6) to 2.11.1-0ubuntu7.7
libc-dev-bin (2.11.1-0ubuntu7.6) to 2.11.1-0ubuntu7.7
libc6 (2.11.1-0ubuntu7.6) to 2.11.1-0ubuntu7.7
libc6-dev (2.11.1-0ubuntu7.6) to 2.11.1-0ubuntu7.7
libc6-i686 (2.11.1-0ubuntu7.6) to 2.11.1-0ubuntu7.7
libcairo2 (1.8.10-2ubuntu1) to 1.9.6-6~mrw4
libcairo2-dev (1.8.10-2ubuntu1) to 1.9.6-6~mrw4
libgegl-0.0-0 (0.0.22-0ubuntu4) to 0.1.3-2010091001~ll
liblcms1 (1.18.dfsg-1ubuntu2) to 1.18.dfsg-1ubuntu2.10.04.1
10.04

    I went through the descriptions of the listed packages in Synaptic, and figured what was causing it. It was libcairo2. And this (and -dev) was the only package from an unofficial ppa. So I downgraded the two packages like so:

    sudo apt-get install libcairo2=1.8.10-2ubuntu1 libcairo2-dev=1.8.10-2ubuntu1

    then restarted X-server and now it's back to the rendering style.
