Does yours not do this?
Please be aware that metacity has actualy two modes of operation: one is the regular mode and the other is the compositor mode. You can control what mode it using by looking with gconf-editor at the key /apps/metacity/general/compositing_manager
In the regular mode it just works as a regular plain old WM and the alt-tab shows only icons.
In the compositor mode it uses the X11 Composite extension to do some fancy effects with windows, most prominently a drop shadow below windows and semi-transparent windows for those that require it (i don't know of any application that does require that thought).
One other important effect of the compositor mode is that the alt-tab dialog will display screenshots of the windows instead of just icons.
This works also for windows that are minimized because in compositor mode metacity saves the pixmap for a window before it's minimized (it does not normally do that in regular mode, unless patched with a patch like the one we used to have for the unity-2d session).
Hope this helps, -- Ugo
