Multiple monitors with different resolution: window maximization broken

[The Fiddler]

I have a 1366x768 laptop that I connect to an external 1920x1080 monitor.

Windows maximize correctly on the monitor that is up or left. Windows maximize incorrectly (they half-disappear into the void) on the monitor that is down or right. It doesn't matter which monitor is set as primary.

Steps to reproduce: connect a second monitor and select a different resolution than the first monitor. Set vertical layout (one monitor over the other) or horizontal layout (side-by-side). Open one window on each monitor. Click the maximize button and observe the brokenness. Try using the grid plugin and observe the brokenness (windows on the bottom or right monitor half-disappear outside the monitor).

Anyone know any fixes/workarounds for this, other than falling back to classic mode? I am using Ubuntu for work and this is hurting my productivity.

Apparently I'm not the only one with issues...

In my case I can't even resize the windows in the laptop screen. The application of the window crashes (killed).

To resize a window I must drag it to the external display, resize, and move down to the laptop screen.

Maximizing in the laptop screen throws the window to the topbar, making it invisible. Had to find it and drag it with alt+mouse somewhere else, and resize it.

Ubuntu Natty, Unity.

Other than that, if it was not for the not_supported Optimus (Intel+nVidia) it would be working great.
