I do not agree that this is ATI only. After upgrading an Intel mobo using on-board Intel graphics from 14.04 to 14.10, I got the same problem. It is not connected with any one font. dpkg-reconfigure fontconfig did not help; neither did removing /etc/fonts/fonts.conf.
What does fix it, but only 95%, is turning off hinting. I used the Unity tweak tool. I can still find a stray example of bad characters here and there. I am running the classic, not Unity interface. Tested with apps: FireFox, Chrome, Thunderbird, Gimp, Inkspace, Libreoffice all of which had the problem. The fonts look a lot better with hinting turned on! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/554935 Title: fontconfig corrupted fonts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/554935/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
