As peke said in comment #30: It's fixed in Firefox 19 (thanks!) but it can still happen when using hardware acceleration.
I turned on layers.acceleration.force-enabled today (Firefox 20 / Ubuntu 12.10 64-bit / nvidia 310.14) and started noticing the issue again. I can see it clearly in gmail, and the strange thing is, that it's temporary: font hinting is strange when scrolling, and after you stop, in 2-3 seconds it jumps to being ok. I'm now attempting to record a screencast to show this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1097763 Title: Firefox 18 anti-aliasing does not render correctly some text To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1097763/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
