Comment 3 for bug 854556

installed fresh copy of oneiric and this issue is getting worse. Expo with twinview is completely unusable. I have attached a video of how bad it is. Al the screen tearing and flicker in the video is what i actually see. The bad drawing or the screen on the right is how it looks to me as well. When you see my mouse moving wildly left and right or diagonally, thats me trying to click and drag an app. Fails most of the time. This problem does not occur when I have a default xorg.conf and only one screen. Then I must admit the expo mode and app drag and drop is pretty slick. Looks awesome. So comparing that to my twin view experience it's a major difference.
