When I start my computer and open Nautilus from menu, panel or favored. It will cause my mouse cursor be busy (animation only) for 15 second. I can still use nautilus, just fine.
This will not happen if you start Nautilus from desktop by clicking home or your computer icon. Also if you logout your user to login screen and then back, issue is gone.
This will happen at least in Cinnamon and Gnome (MSGE) desktops.
