Does anyone else notice that trackpad pointer movement when running Lion will occasionally be slow or seem to get hung up when doing fine movements?

With 10.6 mouse movement on a unibody MBP was always fluid. Predictable acceleration and a very proportional feel.

Within an hour of using Lion I'm noticing that while sweeping movements seem the same or similar, often when making smaller movements the pointer will move far too slowly and that proportional feel is lost. This behavior seems random, like a hiccup of sorts, because just as quickly as it happened, it will disappear and thing will go back to "normal."
