screenshot of the misrendered checkbox

On my Sandy Bridge laptop with linux-3.6.11 and intel-2.20.17, the check in a JCheckBox is sometimes rendered incomplete.

Steps required to reproduce the issue:
1. Compile the attached source file: javac CheckboxTest.java (or run the binary)
2. java CheckboxTest
3. The check is initially rendered correctly. When the mouse is slowly moved over the checkbox' text, some highlight-effect appears which causes the check to corrupt sometimes.

I just noticed the rendering issue is hard to spot ;)
When misrendering occurs, the diagonal line of the check is not connected to the vertical line of the check.

Right, it is one I noticed awhile ago with the SwingDemo. If you move one of the windows behind the checkboxes, the tick appears clipped. Probably a CapLast vs clipping bug.
