Summary border-radius incomplete/rough causing rendering issues

Tested with chromium build 36133 Hi, The issue is (probably) with -webkit-border-radius. I already noticed that the resulting radius render seems a bit rough compared to how firefox renders it. That alone wasn't an issue but there is an issue when you for example use a white to red gradient. Then that rough border radius will get a few pixels that are drawn in red. Here is the Proof of Concept: http://mageprojects.com/purecss/webkit_border_radius_bug/ index.html =================== <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>testing pure css</title> <link rel="stylesheet" href="style.css" type="text/css" /> </head> <body> <div id="container"> <div id="testbox"> <br /> </div> </div> </body> </html> style.css =================== div#testbox { border: 1px solid #bdbcbd; position: absolute; left: 0px; right: 0px; top: 0px; bottom: 0px; border-radius: 10px; -moz-border-radius: 10px; background: -moz-linear-gradient(-90deg, #ffffff 60%, #ff0000); background: -webkit-gradient(linear, left top, left bottom, from(#ffffff), color-stop(60%, #ffffff), to(#ff0000)); } div#container { border: 2px solid white; -moz-border-radius: 12px; border-radius: 12px; -webkit-box-shadow: 0 0 4px #bdbdbd; -moz-box-shadow: 0 0 3px #bdbdbd; width: 502px; height: 132px; position: relative; } Compare it with how firefox (>= 3.6) renders it. Also it seems like the borders from border-radius are anti-aliased in firefox but are not in webkit. Perhaps it's nice to anti-alias it in webkit as well? Ragards, Mark
