Those upstream fixes (https://gitlab.gnome.org/GNOME/gnome- shell/issues/349) were actually authored by Canonical. They will appear in Ubuntu when we ship gnome-shell 3.32 (likely Ubuntu 19.04).
Note however the high CPU (not the animation smoothness) fix (https://gitlab.gnome.org/GNOME/gjs/merge_requests/236) is being backported already, in bug 1803271. In hindsight though I could have used this bug instead... Also, given how simple the fix for the animation smoothness is (https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/253) then I think yes it would be easy to get that backported to existing Ubuntu releases. ** No longer affects: mutter (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750197 Title: App grid animation causes heavy CPU spikes and dropped frames in Wayland & Xorg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1750197/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
