Choosing windows with vertically-stacked monitors

[Luke Scharf]

When running Unity with stacked monitors (laptop display on the bottom, external monitor above), the window-picker sometimes clusters the available-windows directly over the split between the two monitors.

I've observed this happen when I use the meta-W key to pick windows as well, so this is presumably a Compiz bug? Does Compiz provide the picker that lets you pick between the windows in an application?

My description is a little bit vague, since I'm new to Unity and I'm not quire sure where Compiz ends and Unity begins. I have, however, attached a screenshot showing the problem. Hitting "print screen" brought the "System Settings" window, so I'd like to direct your attention away from that window, and toward the upside-down (and unpickable) windows near the middle of the screenshot.

To reproduce:
1. Run Unity in a configuration with a large monitor on the top, and a smaller monitor on the bottom.
2. Open an application that uses multiple windows, such as Chrome or Thunderbird and open several windows.
3. Click on the application's icon in the dock.
4. Observe the windows floating in the least pickable place on the desktop (right between the two screens, and underneath the indicator applet).
5. Try to pick a window. Windows may be unpickable.

I've been trying to figure out if I should call this one intermittent. It doesn't happen all of the time but, I can't remember if it's intermittent and starts happening after a few minutes of uptime, or if it's changed with a recent update. In any case, it's happening pretty consistently now.

BTW, I'm really enjoying running this beta and being a peripheral part of this process!

Does this still happen in Precise (or Quantal)?
