I am now able to replicate my video freeze by lowering and raising windows at a fast pace. When doing this my screen will 'flicker' for an instant and at times will continue to flicker. The flicker consists actually of two areas on the screen. I've tried to capture a screen shot when the continuous flicker is happening but as soon as I raise the window for Gnome screen shot the flicker stops. Tonight when lowering and raising windows at a fast pace the freeze occurred. Running
