Ubuntu(or maybe just Unity) lags whenever I minimize a window when there's no other opened window(others are minimized).

I faced this problem after I install Ubuntu Tweak 0.7, Conky, OpenJDK 7, IcedTea 7 (if it does matter)

There's no problem to:

show and hide windows
spread window
open and close window

I have set window minimize animation as Fade 220ms and Animation Time Step as 1 in CCSM but I honestly don't think this is the problem because when there's other opened window, everything is smooth.

Ubuntu 12.04, Dell Inspiron 1525, Intel Core 2 Duo @2.00GHZ, 4GB RAM
