Title:
[regression] Much higher CPU during some gnome-shell operations
Status in gjs package in Ubuntu:
Fix Released
Status in gjs source package in Bionic:
Fix Released
Status in gjs source package in Cosmic:
Fix Released
Bug description:
[Impact]
Since fixing bug 1672297 in release 18.04 we experience much higher (almost
double) CPU usage during gnome-shell JavaScript operations, such as the icon
spring animation [1]. Even just moving the mouse is a little more expensive now
[2].
[1] https://gitlab.gnome.org/GNOME/gnome-shell/issues/349
[2] https://gitlab.gnome.org/GNOME/mutter/issues/283
[Test Case]
Use 'top' to measure the CPU usage of the gnome-shell process while
tapping Super+A repeatedly. It should be much lower with the fix than
without.
[Regression Potential]
Low. This particular fix is tiny
(https://gitlab.gnome.org/GNOME/gjs/merge_requests/236) and has been
released and used in a couple of upstream gjs versions already without
issue.
[Other Info]
The fix is already released to 19.04 as part of gjs version 1.54.2-1.
And already released to 18.10 as part of gjs version
1.54.3-1~ubuntu18.10.1.
