Can you describe step by step what you are doing and what you see? The place I see it *most* is with the app picker, if I:

 A) Click on the app picker grid icon in the overview
 B) Immediately move the mouse cursor away

Then I see the something like:

 Mouse cursor freezes for a fraction of a second
 Mouse cursor moves onces
 Mouse cursor freezes again for a smaller fraction of a second
 Mouse cursor moves with a bit of a stutter for the remainder of the animation

But it's all pretty subtle, and if I did what is natural to me and didn't move the mouse cursor at all after clicking the app picker. That doesn't really correspond to what the original poster is saying where the mouse cursor seems ot have problems in any sort of animation, or what Jonas is saying where it sounds like he is seeing a big problem.
