Ok, I've managed to reproduce this problem and have a monitors.xml that reliably produces it for me.
The 1366x768 configuration for my laptop does not seem to work when I have a 1920x1200 monitor attached. When the 1920 monitor is attached, the laptop works when it is set to 1360x768. I'm not sure what the difference is other than those 6 rows of pixels. I have it hooked up to a 1280x1024 external monitor right now and the 1366 resolution doesn't seem to cause a problem.
