Xorg log

When using metacity's composite manager, windows moved from my primary head
(LVDS) to the second head (DVI-D-0) do not appear at all.  The mouse pointer
appears correctly, and the pointer changes depending on the contents of the
invisible window as normal (ie: a text-caret when over a textbox, etc).

This happened with the switch to metacity 2.21.8.  One of the changes to the
compositor was to use the Composite Overlay Window.  The kwin's compositor in
KDE4 also exhibits the same behaviour.

Composite works correctly when using xcompmgr, which leads me to suspect that
it's a problem with the COW on the second head.
