If I understand right the screensaver raises the magnifier window only
when it asks for the password? I tried here with xscreensaver and with
gnome-screensaver (in the last the authentication mechanism isn't
working) and anyone raise the magnifier window.

I only have it raised when using the OverlayWindow, but this is a
standard behavior, and when running OpenGL screensavers these interfere
in the magnifier window.
