Bug description:
This started to happen with Ubuntu 19.10.
When an animated gif is displayed in a browser, gnome-shell begins
using 100% CPU on all cores.
To reproduce:
1) open Firefox, or Chromium
2) load an URL where an animated gif is displayed - you can also use
this direct link to https://i.stack.imgur.com/h6viz.gif
3) gnome-shell will start using 100% CPU on all cores (as long as
Firefox/Chromium window is in the foreground)
