--- Comment #14 from Alexandre Demers alexandre.f.demers@gmail.com 2012-08-25 03:56:27 UTC --- MLAA seems to be doing exactly as under Windows. I saw the same thing with Catalyst on Windows 7 mostly in Messenger. See http://www.sevenforums.com/software/182520-msn-live-messenger-browser-proble..., http://www.sevenforums.com/software/182520-msn-live-messenger-browser-proble... and comments in http://www.sevenforums.com/graphic-cards/166423-text-looks-if-water-has-been...
So, for some reason, MLAA doesn't behave as expected with some applications (2D content where it "shouldn't")
