Public bug reported: Go to this page, and you will notice a problem that occurs on other pages intermittently: unless you scroll up and down fast, the "pts" logo at the right of each test appears distorted. I had noticed this in other images in Firefox too.
http://www.phoronix.com/scan.php?page=article&item=macosx_lion_precise&num=5 In Chromium, it doesn't even show this logo, but that is probably just another Webkit bug. I had noticed other sites where images show up as bands of color, until you scroll up/down to refresh the image. This could be a bug in Ubuntu's display system, or possibly a Firefox 20 bug?
