The comments section is in an iframe with:

    -webkit-backface-visibility: hidden;
    -webkit-perspective: 1000px;
    -webkit-transform-style: preserve-3d;
    -webkit-transform: translateZ(0);
    transform: translateZ(0)

I think the fuzziness on retina is because we need to set rasterizationScale on a CALayer.
