Gnome-Shell abnormal CPU use
Last modified: 2018-07-28 10:41:11 UTC
Gnome-shell use allways more 25% of my 4 core CPU Tell me what you need in information. I'll post it
See https://bugzilla.gnome.org/page.cgi?id=bug-writing.html for basics (steps to reproduce, version and distribution information), and https://live.gnome.org/GnomeShell/Debugging for shell stuff :)
Have the same issue. I use 3 machines, all of them have the same problem. High CPU usage from gnome-shell. All of them have different HW configurations. Two of them uses multi-monitor configuration, but issue seems to be not connected to this aspect.

On my EeePC it prevents me from watching HD movies. When I switch to xfce everything is working like a charm. When I strace the shell_gnome I got: sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 sched_yield() = 0 Why gnome_shell constantly spin on sched_yeld ? What idea is behind this ?
That was a long time ago and performance has been improved significantly in the meantime. Do you still witness this issue?
