I disabled all extensions in Firefox. I'm trying to fix my high CPU. I'm
not a computer adept.

Before installing 18.04 my CPU load averages ranged from .5 to 1-ish.
Now they are always over 2. That's not a heat issues, obvs, but it is
making for erratic mouse/screen appearances.

Title:
High CPU usage by gnome-shell when only running gnome-terminal
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Even when doing nothing but displaying a terminal screen with top
running gnome-shell uses 10% of a CPU. That seems excessive. I
disabled all extensions to try and make the test fair. Enabling the
system monitor extension increases the load to 13-14%. It seems that
the gnome-shell screen painting is highly CPU consuming even if screen
updates are infrequent (1 a second for all these cases).
