Bug Description
Upstream Issues:
https:/
https:/
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.

Upon further investigation, I can confirm that this issue only affects the App Drawer. Minimizing and Maximizing windows, and etc are all buttery smooth.
