Cairo Composite Manager

When changing the desktop to an application which was started _before_ cairo-compmgr and swichting to an empty desktop the application window is still shown.

I made a screencast showing this problem: http://spamt.net/~uli/cairo-compmgr.ogv
Im switchting from desktop 4 to desktop 3 with kontact running, and after switching back to desktop 4 kontact is still shown. After quitting cairo-compmgr the window disappears.


Im running cair-compmgr from the master branch (c6a9a9918ab10544db1c8eef89293b095f2f1bb6) and using awesome 3.3 as window manager.

Attached the output of xwininfo -root -children
xwininfo: Window id: 0x114 (the root window) (has no name)
