Consulted the bug on #gnome-shell IRC. Next step is to track down the event that actually triggers execution of cogl_glib_source_dispatch. It's possible it simply does not arrive. BTW, this does not rule out Xorg as potential culprit, it might be simply not delivering the expected event. This is yet to be checked.
