Description Robert Adams 2012-01-27 13:18:58 PST 
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.

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.

I think that it's actually an issue regardless of opacity. Try e.g. on this page:

1. Mark "Add me to CC list" 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.

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