I can confirm this behaviour too. It seems to apply on images that are downscaled either with CSS or the width and height attributes of img tag.
I see this for example on http://guardian.co.uk frontpage and when I zoom out with Ctrl+- almost on any page. Mozillazine forums has a thread about the problem too: http://forums.mozillazine.org/viewtopic.php?f=9&t=1042335 -- [intrepid] alpha 6 - Image rendered with border in Firefox https://bugs.launchpad.net/bugs/274575 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
