The issue seems to be that the gnome-screensaver watches for "visibility_notify_event" in gs-window-x11.c

For unredirect fullscreenwindows it get:

[gs_window_real_visibility_notify_event] gs-window-x11.c:2059 (21:02:19): gs_window_real_visibility_notify_event(): 7bf080 unobscured
[gs_window_real_visibility_notify_event] gs-window-x11.c:2059 (21:02:19): gs_window_real_visibility_notify_event(): 7bf080 fully_obscured
[gs_window_real_visibility_notify_event] gs-window-x11.c:2059 (21:02:20): gs_window_real_visibility_notify_event(): 7bf080 unobscured

but without "unredirect fullscreen windows" its:
[gs_window_real_visibility_notify_event] gs-window-x11.c:2059 (21:07:02): gs_window_real_visibility_notify_event(): 7bf260 unobscured

Now in gs-manager.c window_obscured_cb () is run and it tests if the window is obscured. If that is the case, it requests a unlock.
