Public bug reported:
Ubuntu Release: 17.10
gnome-shell version: 3.26.2
System Theme: CommuniTheme Beta
Upon navigating through various areas of the system, GUI animations are
very stuttery. This heavily affects the CPU usage of my device. For
instance, opening the shell app drawer displays a very janky animation,
and my CPU will spike to nearly 85% for each open/close. This happens
regardless of using XOrg or Wayland; however Wayland appears to have an
overall lower impact on resource usage. The CPU in this laptop isn't the
greatest (being a 2014 Celeron), but this is noticeably more sluggish
compared to previous releases like 16.04 and 16.10.
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.
