------- Additional Comments from opendarwin.org at mitzpettel.com
This patch fixes both the "freezing" and the red 1px stripe.

The repaint test shows excessive painting being done. That's not a result of
this patch, though, so I think it can be left for a separate bug. The same goes
for the buttons in the original test showing a repaint glitch when their
content changes.
