** Description changed: [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. + 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.
