Windowserver takes too much CPU
Windowserver takes about 30-48% CPU (usually during scrolling but basically during any graphical activity).
OS: 10.7.2
HW: 13", Mid 2009, 2.53GHz C2D, 8GB RAM DDR3
Resetting PRAM and NVRAM didn't help. I've tried to uninstall Parallels Desktop 7 but it didn't help. I have another MBP late 2008 that runs without that issue.
Do you know what could be the reason and how to fix it? Or at least how to trace the issue (debug mode of windowserver or dtrace etc....) Thanks a lot.
