Public bug reported:

Binary package hint: compiz

To reproduce:

- Configure Compiz to use a 3x3 grid (or something similar) of viewports
(the Desktop Wall plugin)

- Open several windows on different viewports

- Switch between viewports using Viewport Switcher plugin hotkeys

- Observe that sometimes the windows on the viewport you switched from
become hidden. Switching back to the viewport, they reappear only on
Alt+Tab.

- Sometimes, they also reappear when switching viewports again, or
invoking Expo.

This is with Unity, so I cannot distinguish between minimized and
"disappeared" windows.

Note that this occurs on a relatively slow Asus EEE mini-notebook. I
don't recall seeing this on my faster computer with a similar Natty
setup.

Title:
  Windows become hidden/minimized when switching viewports
