Sorry I'm totally newbie here and with ubuntu, but I regularly face the same
problem with Ubuntu 17,10 in Virtualbox, when I run eclipse:
Version: Oxygen.2 Release (4.7.2)
Build id: 20171218-0600
Either this happens at startup of Eclipse, or after a while with no obvious
reason...
Seems this
This bug is affecting me as well. I just ran `ubuntu-bug gnome-shell`,
hopefully you can see my files?

Title:
High CPU usage in gnome-shell
Rasmus: I think other people have reported performance problems with the
Activities overview already. Maybe you should join bug 1698792 to
discuss that one. I think upstream Gnome bugzilla has reports of it too.
Let's keep this one about gnome-shell's CPU usage while Firefox is
running.
It's
The above bug seems to be solved or at least mitigated a bit. With just
having firefox up the CPU usage of gnome-shell is between 2-5%.
Gnome shell is still much less performant than Unity though, by moving
windows, open Activities or dragging the mouse over the dock its CPU
usage quickly jumps
This bug is probably a bit out of date now. I don't see problems as bad
any more.
Rasmus: Please test again with the latest firefox (I think the newer
versions ~57 or so are much more efficient). And if you can, also test

I think this bug is about the single monitor case. Please open a new bug

I also experienced increases load on my laptop with an external monitor
in addition to the built-in screen. The load is low initially, then
increases such that the fan turns on. Disconnecting the extra monitor
reduced the load 30s after unplugging for me.

Title:
High CPU usage in gnome-shell just redrawing the screen (Firefox is
running)
It affects me too.
I'm on Ubuntu 17.10. Closing all apps but System Monitor, then moving
the mouse up and down on the icons in Dock bar, keeping on, and my
i7-8700k will be rapidly consumed 80+% even 90+%.

It appears the high CPU of gnome-shell with totem on Wayland at least is
due to the totem app window redrawing at 60Hz seemingly only on Wayland
(bug 1698282). When this happens, the compositor will have to upload
(copy) the window texture from CPU to GPU 60 times per second, which is
