Cinnamon 2.0.2 and all earlier versions I've used seem to do an excessive amount of processing when click-dragging windows.

This manifests as a slight, but noticeable stutter when sliding the window around, which makes the desktop experience seem laggy - it's extremely noticeable when I boot from Cinnamon into Windows 7, where windows slide around smoothly.

If I monitor the cinnamon process with top, I can see the CPU usage while not dragging, but doing something like playing a YouTube video sits at around 5-10%. The moment I start dragging a window (a Chrome window full of text) - cpu usage jumps to about 30%.
