http://people.freedesktop.org/~kwg/fluid.trace I replayed an apitrace on Intel and nVidia a while back. IIRC, 1x1 green pixels appear in the starting image. On nVidia, those get blurred/filtered out near the start. On Intel, they don't, and so the actual algorithm of the demo seems to perpetuate them in odd ways. I haven't looked into it further, so someone is free to pick this bug up.
