Has anyone else seen this issue? It has only been reproduced on Thunderbolt-equipped Macs while attached to Cinema Displays (Either Mini-Display Port or Thunderbolt). If you are able to test this on both Thunderbolt and Non-Thunderbolt Macs as well as Cinema and Third party displays, please leave the results of your testing in the comments. I find that it is easiest to reproduce if you move the cursor in a circular motion and then run the command. This makes it painfully obvious when the jerky-cursor behavior hits. Check out details on this issue over on Kyle’s Blog.
