Lightdm "Flicker" im Login Screen?

Hey, ich habe zurzeit Arch installiert und nutze Lightdm mit dem Lightdm-gtk-greeter als Greeter.

Wenn die Passwortabfrage erscheint dauert es etwa eine Sekunde und dann läd der Login Screen neu. Ist es nur ein kurzes Flickern, aber es unterbricht die Passworteingabe und nervt irgendwie.
Hier mal der /var/log/lightdm.log:

Ich habe schon Lightdm und den Greeter neuinstalliert und versucht es downzugraden. Das gleiche mit Gtk3. Allerdings half das alles nichts.
