GNOME Bugzilla – Bug 772977
Gnome Shell 3.2x.x ineffectively using GPU and High CPU Usage
Last modified: 2021-07-05 14:28:27 UTC
This is a similar case but has not been resolved until now on Gnome 3.18 - 3.2x.0 I used a fairly powerful PC but I found out that just by doing something, for example, moving the mouse on activities to show all apps running, gnome-shell spikes up to 18-32% cpu usage on the other GPU does almost nothing (as can be seen from Nvidia X Server monitor). It is known that gnome-shell does the rendering, If I got the a GPU, then the rendering should be done in the GPU, but still the spike shows in the CPU as what TOP and system monitor says. Gnome-shell therefore ineffectively uses GPU and is clearly a bug on its inefficiencies on GPU enabled devices. How do we fix it? Processor: 2x Intel Xeon E5 2670 2.7GHz 8C/16T GPU: Nvidia GTX 1060 6Gig MB: Asrock EP2C602 4L/D16 Mem: 32G Samsung ECC Server type SDD: Samsung Evo 850 500G (Not the buggy Evo 840 of course) HDD: Hitachi 1T

This is probably best handled as a duplicate of bug 683204 or bug 737958.
Hi, similar too previous versions
Those are only CPU related, Gnome-shell should offload all rendering to GPU.
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org. As part of that, we are mass-closing older open tickets in bugzilla.gnome.org which have not seen updates for a longer time (resources are unfortunately quite limited so not every ticket can get handled). If you can still reproduce the situation described in this ticket in a recent and supported software version, then please follow https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines and create a new ticket at https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/ Thank you for your understanding and your help.
