[Spice-devel] Problem with dual-display full-screen client on X

I am running the guest OS (CentOS) with dual heads.
I am also running the client on CentOS.
When I open the client, two client windows appear (spice0 and spice1),
and all is well with the world.
The machine I am running the client on has two monitors, and is XRandR
When I press Ctrl-Shift-F11 to change the guest to full-screen, both
monitors change resolution, and the spice0 window properly appears in
full screen mode on the left monitor. The spice1 window never appears
anywhere, and the right monitor goes black with an "X" cursor on it.
I did some debugging, and it appears as though my window manager may
be interfering with the clients attempt to use the second monitor.
In the client code, RedWindow::show() calls RedWindow::move() to
move the right client window onto the right monitor.
RedWindow::move() in turn calls XMoveWindow(), but the XMoveWindow
call appears to be ignored. I suspect it is being intercepted by my
window manager, because if, right before I call RedWindow::move(), I
set the override_redirect attribute of _win to "true", it works fine.
(I then set it back to "false" when we leave fullscreen mode).
So, this appears to fix it... but is it the right fix? Or have I just
patched a symptom of a deeper problem?
