For me the problem is there in Hardy Alpha 4 (Intel 965 adapter). In Gutsy, enabling 3D acceleration prevented screen refresh after rotate. In Hardy, enabling 3D acceleration but disabling compiz solves the problem. However, when compiz is enabled, the screen doesn't refresh after rotate, making it impossible to use compiz + tablet functionality.
