Created attachment 196537 [details] html file demonstrating the bug A specific combination of large fonts with fixed positioning causes stuttering, ugly artifacts, incorrect cropping and erroneous z-indexing. I've attached an html file to illustrate these problems. Firefox and Chrome on desktop have no problem rendering the page. However, most mobile browsers break in some way, including webkit-backed ones. Some of the problems: * The tiled background does not stay fixed * Text on a lower z-index appears in front for some time, becomes correct after some sort of refresh occurs * Artifacts appear after scrolling down pretty far, and scrolling back up
Created attachment 196538 [details] video footage of broken page on mobile :( This is video of interaction with Firefox, but Chrome reacts *very* similar.
