In OS X Lion 10.7, when using Safari, I double tap content and it is zoomed. Everything works well, but some of the fonts seem jaggy. There is no anti-aliasing when zoomed. Pulling back to actual size, everything looks nice and smooth again.
Even on this page, the text I write in the comment box is anti-aliased, but the preview text looks jaggy.
How do I force it to anti-alias text when zooming in?
