Could not find Application Dashboard category, putting this here instead. The blur used in application dashboard is very weak, inconsistent with the blur on the logout screen and looks slightly pixelated.

Yes, it's a different blur method used for speed purposes. Lock and logout should have used that method too, if it wasn't for a bug which is recently fixed.
