** Description changed: - https://gitlab.gnome.org/GNOME/gnome-shell/issues/55 + Upstream Issues: + https://gitlab.gnome.org/GNOME/mutter/issues/232 + https://gitlab.gnome.org/GNOME/mutter/issues/233 Ubuntu Release: 17.10 and 18.04 - gnome-shell version: 3.26.2 - System Theme: CommuniTheme Beta + gnome-shell version: 3.28.2 + System Theme: CommuniTheme - 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. + 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.
