Firefox cutting holes in gedit with Metacity

The problem happens with every version of Thunderbird from 1.0 to the current
8.0, as well as Firefox. It happens with every version of Wine I tried from 0.9
to the present. I did not test versions of Wine older than 0.9.

The problem does not occur if I run Firefox or Thunderbird without a window
manager:

/etc/init.d/gdm stop
xinit wine thunderbird.exe

If I change my window manager to Metacity ("metacity --replace &") then instead
of leaving gray areas on the screen, a slightly different but related bug
occurs. First position Firefox (or Thunderbird) over another window and click a
few menus. Then move Firefox off the second window, let go, and start clicking
the menus. Rectangular holes corresponding to the menus clicked when Firefox
was covering the window will be cut in the window that it used to cover,
allowing the desktop background to show through.

With Metacity, enabling composting effects via "gconf-editor
/apps/metacity/general" makes the problem go away.
