Please describe the problem:
metatcity is configured for "action_double_click_toolbar" to be toggle_shade and
nautils is stopped and has "background_set" to false such that xroot is a real
colour and not taken over by nautilus (such that "xsetroot -solid slateblue4"
actually changes the color)

when you double click a window, it will become shaded but the wireframe exists
drawn on the desktop/root window and only disappears if you drag another window
over the wireframe -- something is not getting refreshed correctlh

Steps to reproduce:
1. metatcity is configured for "action_double_click_toolbar" to be toggle_shade
2. nautils is configured for "background_set" to false
3. disable nautilus from running and quit metacity and restart
4. xsetroot -solid slateblue4
5. start an application (xterm etc)
6. double click toolbar to shade window

Actual results:
wireframe of window is still shown even when the window is supposed to be shaded

Expected results:
shaded, wireframe not visible

Does this happen every time?
yes
