Description of issue: The GUI seems to freeze/reload/refresh instantly. It
happens when I e.g. click on the docker panel and/or just move the mouse cursor
around, click on apps and do something GUI related, open folders. The GUI
reload/refresh crash lasts for about 2 seconds, it suddenly/instantly
repositions my mouse cursor to the lower right corner of the screen and my
laptop's fan works harder at those 2 seconds. The issue started after I updated
and, at a later time, rebooted the machine.
Below are the gnome-related upgrades that I did (`cat /var/log/dpkg.log |
grep gnome`):
