That the bug is about incorrect subpixel rendering, sometimes (on the most typical screen: horizontal RGB) the fonts are rendered approximately as if the screen was horizontal BGR.
The two screenshots linked so far were created on such systems, hence they exactly represent the problem for those looking at them on horizontal RGB panels. Those who have other systems (e.g. vertical monitors) might not get the same feeling for how it looks. It's recommended to examine the second screenshot (good and bad versions under each other) with a pixel-wise magnifying software, such as xmag. The font looks so bad I just simply couldn't stand it, it really hurt my eyes, I reverted to an older firefox. In my opinion, this is a very severe bug. -- 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/ubuntu/+source/firefox/+bug/1097763/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
