Sometimes the vertical alignment will also waver. This doesn't appear using metacity, so it's not a hardware issue. This also doesn't appear using the next highest resolution (1680x1050). I'm using the radeon open-source driver. lspci -k: 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
