+Subject: [sddm-theme] Prevent the logo from leaking in after a fadeout
+
+Summary:
+Even when the vendor logo is turned off it can be briefly seen when the login screen changes from the fadeout state back into normal.
+
+Comments in other code say that "OpacityAnimator when starting from 0 is buggy (it shows one frame with opacity 1)" so this patch replaces it with NumberAnimation.
+
+There's also a minor fix included - placing the drop shadow sooner in the hierarchy because it should be drawn underneath an object, not in front of it.
+
+Test Plan:
+Reduce the fadeout time to something small and then:
+
+`sddm-greeter --test-mode --theme /usr/share/sddm/themes/breeze`
