User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release)
Build ID: 20130910160258

Steps to reproduce:

Give an element background-clip: padding-box and make sure it has a background-color with a low opacity border and border-radius (see testcase)


Actual results:

There's a gap between the elements background and border. The color behind the element mixes with pixels where its border and background touch.


Expected results:

See attached testcase, no white from the document background should be visible where the elements border and background connect.
Confirmed greyish pixels with 2013-10-28-03-02-05-mozilla-central-firefox-27.0a1.en-US.linux-x86_64.
