** Changed in: gjs (Ubuntu)

** Description changed:

- Since fixing bug 1672297 in release 18.04 we experience much higher CPU
- during gnome-shell JavaScript operations, such as the icon spring
- animation.
+ [Impact]

+ Since fixing bug 1672297 in release 18.04 we experience much higher
+ (almost double) CPU usage during gnome-shell JavaScript operations, such

** 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.
  
- The fix for this regression is
- https://gitlab.gnome.org/GNOME/gjs/merge_requests/236
+ [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/Medium. This particular fix
+ (https://gitlab.gnome.org/GNOME/gjs/merge_requests/236) has been
+ released and used in a couple of upstream gjs versions already without
+ issue. The real regression potential comes from other bug fixes included
+ in version 1.54.2
+ (https://gitlab.gnome.org/GNOME/gjs/blob/gnome-3-30/NEWS). Although they
+ are only bug fixes.
+ 
+ [Other Info]
+ 
+ The fix is already released to 19.04 as part of gjs version 1.54.2-1.
