[Bug 1764137] [NEW] [bionic][beta][nvidia] gnome-shell high cpu utilization

[Dmitrii Shcherbakov]

Public bug reported:

I am experiencing 60% - 200% CPU utilization after an upgrade from
ubuntu artful to bionic.

Pretty much any drawing results in a sluggish behavior due to high CPU
utilization.

The same combination of kernel/drivers did not result in the issue on
17.10 so gnome-shell seems a good candidate to blame.

A bit odd that I cannot reproduce this on a fresh 18.04 installation on
the same system.
