Multiples copies

The "new" Steam UI running under Wine has a weird effect when run along with a
compositing window manager. Instead of one copy of the window, multiple copies
appear tiled to the right and down. Only the top-left copy is "solid" in the
sense that it's the only one that receives events. Clicking on a copy sends the
events to the window below (another application or the desktop). All copies
reproduce the changes in the main copy.

I've reproduced this with Gnome-Shell, plain Mutter, and Metacity in
compositing mode. Metacity with compositing mode disabled doesn't exhibit this
problem.

I'm attaching a screeshot made with Gnome Shell. Metacity shows a different
effect: instead of the extra copies, it shows filled black.

Curiously in the "expose" mode of Gnome Shell (i.e. when the desktop is zoomed
out) the window appears correctly. I haven't tried similar features of the
other window managers.
