Bug Description
After turning on an external monitor, the window decoration disappeared on one of my open windows.
To reproduce:
1) Boot 12.04; login
1a) (optional?) Work for awhile - browse in FF, email with Thunderbird, use the terminal, etc
2) Launch thunderbird; compose a new message in a new window
3) Plug in an external monitor
4) Launch nvidia-settings; enable the second monitor in Twinview mode (I had to press 'Apply' twice to get the OS to use the external monitor; the first time did not result in anything displayed on the external monitor. I think this is a separate bug)
Expected results:
Desktop/
Actual results:
Desktop/
Maximizing then minimizing the window w/ missing decoration (by double-clicking the place where the title bar should have been) resulted in the decoration being restored.
The external monitor is 1280x1024 while the internal monitor is 1440x900; I am not sure if that is relevant.

Here's a bug with a tight reproducer, logged by an engaged but reporter. Thought Dx would like to take a look.
