Window move framerate bad in OSX 10.8.2

I'm running a MacBook Pro 2012 with 16GB RAM and a 512GB SSD. As my post says, I've got OSX 10.8.2 (Mountain Lion). My adapter is a Kensington Multi-Display Adapter (http://www.newegg.com/Product/Produc...82E16834997695). My monitor's native resolution is 1680x1050, but the MBP 2012 has a lot of processing hardware. I'm not seeing much CPU utilization when the video starts to get all slideshow-y, so I really think this is a driver issue.

Yes - we want to try and improve the performance of DisplayLink devices on the Mac, and we have a number of ideas of ways to improve this. V2.0 release should give us the code platform to be able to improve performance.

Our performance with the same hardware on Windows is much better than Mac, so technically it should be possible.
