Created attachment 67341 [details] HTML file showing the rendering problem Overview: If a div has nonzero border radius and nonopaque border color, darker strokes appear in the corners. Steps to reproduce: Simply open the attached HTML file in Webkit r67077 and then in Safari 5.0.2 and observe the difference. Expected result: See attached file 'Screenshot Safari 5.0.2.png' Actual result: See attached file 'Screenshot Webkit r67077.png' Platform: Tested on OS X 10.6.4 in Webkit 6533.18.5, r67077. Notes: The same problem appeared in some earlier versions of the nightlies, but I don't have numbers. The problem does not appear in Safari 5, Safari 5.0.1, and Safari 5.0.2
