I don't see the window manager mentioned (presuming it is the gnome bundled
stuff).

It's possible that you're exposing yet another bug in compiz.

xterm patch #268 introduces a feature for toggling to full-screen mode,
which I see is triggered in some configurations by the gnome window manager(*)).
That's over a year old, by the way. #269 makes the feature configurable,
e.g., the "fullscreen" resource.

(*) this is a feature of the window manager, not xterm, and would normally
    be addressed by configuring the window manager...

You should be able to verify if it is a compiz bug by temporarily disabling
that aspect of your configuration.
