PAMAC hurts Gnome-Shell performance
Created by: leipero
As title says, after about 23 seconds when gnome session is loaded, whole shell starts lagging, it's always after 23 seconds since "enter" is pressed at GDM login screen, I assume pamac loads something at that time (20 secs after login), the problem is, it is not just check, since performance issue does not go away. Even worse, removing pamac completely doesn't solve the problem, and after reboot issue is back.
