Dark strip at top of launcher icons

[Michael Terry]

Binary package hint: unity

I noticed that there seems to be dark strips at the top of my launcher icons after a while. Screenshot attached.

After playing with it, I believe you can reproduce it by opening two adjacent apps at the same time (click on one, then immediately click on the other). The bottom one will get the dark strip roughly after the top icon's glow animation completes.

Thanks Michael. We've spotted similar rendering issues but they seem to be very specific to the GPU/GL driver combination. Can you detail on which system that appeared?

@macslow: the dark rectangles come and go; can you take another look with Michael?
