Comment 4 for bug 815052

I've seen this on my T61 Thinkpad, with Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) [8086:2a02] (rev 0c), on Natty and Oneiric both. Sometimes this happens after a regular suspend to RAM. Hibernation triggers it more often. I usually see this in various Unity interface elements (lancher tooltips, dash selected item highlighting), see e.g. attached image.
