Webkit Bug #23364

Font anti-aliasing (smoothing) changes when elements are rendered into compositing layers

So I've been plagued with this font rendering bug since Safari 5 was released. Somehow though, (I forget the details already), I seem to remember it also had something to do with installing Flash Player 10.1...

Anyway, You have to look closely to the text in the next paragraph. While the animation is running, the font smoothing (anti-aliasing) is removed from the text. It's restored again when the animation stops.

position:relative;

This text has a background color set so the text anti-aliasing isn't affected by the image animation.

position:relative; background-color:#e9eff5;

This text isn't affected because it's position is not set to `relative` so it defaults to `static`.

position:static;
