Blurry for me to. Safari 6.0.5, Mac.

It's the combination of -webkit-transform and -webkit-backface-visibility that causes the blurriness. Wild guess: those attributes turn on 3D acceleration, and rendering is incorrectly offset by .5 pixels.

Setting -webkit-perspective can also trigger aliasing on transformed elements. 24 ways has a good intro to 3D transforms:

Same here, on Chrome on Windows (haven't noticed when I first looked at the example on a Mac). Also, only some effects leave the text blury. "Let me in" for example, doesn't.

Only the last scroll example on the right, for me.

nope.. same here. chromebox.
