This happens each time, only once, and does not prevent logging in. In fact it is not only a display glitch : if I start to type my password before the blackout, the typed characters are lost when normal display resumes. So lightdm might be restarting. This is only mildly annoying, but I am also experiencing other graphical problems which may be or not be related (namely #1568604).
