AFAIK, gnome-system-monitor is one of those rare apps which are software
rendered (because GTK) but also try to animate at a smooth frame rate.
It's a rare combination and a useful test case.

If I run eclipse from a docker container (with -v /tmp/.X11-unix:/tmp/.X11-unix
), then no cpu overuse.
It might related to that in this case eclipse cannot connect to dbus.

I have this bug, triggered by eclipse on latest Bionic.
I do not see any gnome shells running though.
Do we know any workarounds?

Thanks. That explains a lot. I think gnome-shell is presently too slow
to be able to handle 1080p on a Celeron 847. But we are working on a
bunch of different optimizations that should help in future.

At what resolution though? Please just run 'xrandr' and send us the

Oooh... that makes sense now, thanks.
The problem you are seeing is with mutter/gnome-shell being inefficient
at frequently-updating software rendered windows. This is a known
problem, but until now we only knew of Eclipse triggering it (bug
1756508), and the older pre-Quantum versions of Firefox
I restarted my computer 3 time.I launched FF and the top command. The home page
of FF is https://www.bing.com/?cc=be. I opened a second tab with
maps.google.com. Everything was find. I lauched system monitor and then, the
CPU of one core jumped to 100 %, even after closing the maps.google.com ta
And what web pages are good examples of high CPU usage?
Some web pages should yield zero CPU usage, so this question matters :)

OK. Please reduce the problem down to a single app, like just Firefox. Now,
please let us know:
1. The version of Firefox; and
2. What web page(s) cause the biggest problem.

avenue for helping you because the Celeron 847 h

The CPU seems taken by Xorg (see screen shot). When the gnome-shell proc

I was running Thunderbird, Firefox, System Monitor (and a console with
the top command). But it happen too with no app launched or just
Firefox.

1. Are you running any apps when the CPU usage is high?
2. What does 'top' show when the CPU usage is high?
