Ok, I have solved this one. It is caused by a bad interaction between
gnome-session's logout dialog box and xcompmgr. When the dialog is
displayed, xcompmgr is frozen and so the screen will no longer update.
It turns out the keyboard *does* work, but without the screen updating I
didn't notice. :)

(The xlsclients breakage is also caused by gnome-session's logout dialog
box, BTW.)

The same behaviour can be caused by sending xcompmgr SIGSTOP, including
the blank screen when switching away from X and back again.

I'm not reassigning the bug since I don't know whether this is the fault
of gnome-session, or of xcompmgr.
