It seems the fix is upstream already in the gnome-3-28 branch, but
didn't appear there early enough to make it into bionic-proposed version
3.28.3+git20190124-0ubuntu18.04.1 :/
** Changed in: gnome-shell (Ubuntu Bionic)

Bug description:
Upstream Issues:
https://gitlab.gnome.org/GNOME/gnome-shell/issues/349
https://gitlab.gnome.org/GNOME/mutter/issues/233
Ubuntu Release: 17.10 and 18.04
gnome-shell version: 3.28.2
System Theme: CommuniTheme
Opening the Applications Overview (App Grid) displays a very janky
animation, and my CPU will spike to nearly 90% for each open/close.
This happens regardless of using XOrg or Wayland; however Wayland
appears to have an overall higher impact on resource usage.
This same issue is still existent, but somewhat less noticeable on my
other i5-6400 (GTX 1050) machine. Also, emulating this release in a VM
with 2 CPUS and 4096MB of RAM renders it unresponsive for 3-5 seconds
after opening/closing the app drawer.
Please do not hesitate to follow up with requests for more info, as I
will be happy to help.
