Completely unrelated.

Louis-David, my guess is just that GDM enables AA by itself, while your
LightDM greeter does not, and your desktop environment either.

lightdm-gtk-greeter on Debian has xft-antialias=true by default, so that
should be the case, although I don't know if it's propagated to the
desktop environment.

In any case, check in your desktop environment if gnome-settings (or
something like that) is running. My second guess would be that when you
login from GDM, it doesn't clean after itself.
