Display shifts to left after sleep.

I just updated my OS to 10.6.6 on my Mac Pro. After the computer wakes from sleep, the display has shifted to the left of the monitor and the resolution and color have changed.

I have tried system preferences-->Displays and tried to correct the resolution and color, but the display is still not correctly rendered. I use an i1display 2 from Xrite with the most updated version of i1match software (3.6.3) to calibrate my monitor.

Before updating the OS yesterday I was not having this problem.
 
I would check the fans on the video card. Clean them. If the card is not getting proper cooling the video can get messed up.
