1. Please uninstall these extensions:

   '[email protected]',
   '[email protected]',
   'multi-monitors-add-on@spin83'

   and then reboot and tell us if the problem persists. We need to try
this first because so many bugs are caused by extensions.

2. If the problem still happens then next time the gnome-shell process
is using 100% CPU please use:

     kill -ABRT <pid>

   as that should create a .crash file in /var/crash. Then run:

     ubuntu-bug YOURFILE.crash

   to make a new formal bug report.

Title:
  Gnome Shell Freezes

Status in gnome-shell package in Ubuntu:
  Incomplete

Bug description:
  I found when I using the computer time to time gnome freezes randomly,
  when happens I have to press ctrl + alt + f1  to enter to the
  Terminal.

  In the terminal with "top" I saw that gnome-shell was stuck with 100%
  CPU. using "sudo killall -3 gnome-shell" works to restore the desktop,
  but this close all the windows and I loose my not saved work.
