screenshot with Firefox Nightly 2012-07-12
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2b1) Gecko/20091029 Firefox/3.6b1
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2b1) Gecko/20091029 Firefox/3.6b1
when rounded buttons (css) use thicker borders i.e. 10px, there are differences between the background and border render which make the bg colors visible.
there is a rogue black bit outside the rounded edge. This appears to be because the border is being drawn with a different rounding than the div.
Reproducible: Always
Steps to Reproduce:
1.load following html
<html>
<head>
<style type="text/css">
button {
background-color: black;
border: 10px solid white;
color: white;
font-family: sans-serif;
font-size: 20pt;
font-weight: bold;
padding: 2em;
-moz-border-radius: 30px;
}
</style>
</head>
<body>
<button>One</button>
</body>
</html>
Actual Results:
there is a rogue black bit outside the rounded edge. This appears to be because the border is being drawn with a different rounding than the button.
Expected Results:
the border should totally cover the background

Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.3a1pre) Gecko/20091106 Minefield/3.7a1pre I can indeed reproduce this, but it is not something new. I don't see it with Firefox 2, though. And latest Minefield looks worse than 3.0.
