    <thetext>Using Chrome 16 (Webkit 535.7) and Safari 5.1.2, a checkbox (input type=checkbox) element that is checked and has an opacity less than 1 (in this case .5) shows the top border of the checkbox as cut off, in addition to the top of the check being cut off.

    <thetext>It should be noted that this does not occur on any other browsers tested (including a wide gamut) and it is believed that this is a WebKit issue.</thetext>

    <thetext>I think that it&apos;s actually an issue regardless of opacity. Try e.g. on this page:

1. Mark &quot;Add me to CC list&quot; checkbox.
2. Scroll the page up ,so that the checkbox is out of the view.
3. Scroll it back very slowly.

It will be incompletely painted.</thetext>

    <thetext>I believe this is a dupe of bug 75128. How does it look on the nightlies?
