Text in the fixed positioned block with z-index > 0 renders strange when there is any block with -webkit-transform css property present on the page.

I've made a little test page: http://z.nocoffee.ru

<!DOCTYPE html>

		div {
			position: fixed;
			z-index: 1;

		p {
			-webkit-transform: rotateX(180deg);			

	<div>Some text for test that renders strange</div>	
	<p>I'm a block with -webkit-transform</p>

Looks like a dupe of 23364 to me.
