Details

(Whiteboard: DUPEME)

If you look at our rendering of CSS triangles in comparison with other browsers, you will notice that the null border (pointy side) of the triangle improperly renders with a dark outline: http://davidwalsh.name/dw-content/css-triangles.php (take a look at the yellow triangle on that demo page)

If you add a value of "border-NullSideHere: 0 dotted;" it will cause the null border side of the element to render properly. Interestingly, you must use a border-style other than "solid" to trigger the correct render.

Pretty sure this is a duplicate...  it's also not reproducible on Mac, as far as I can tell, which is what makes me think it's a duplicate.
