Performance of window previews is significantly improved in mutter 3.28.4 (which doesn't exist yet :) due to:
https://gitlab.gnome.org/GNOME/mutter/commit/d81dcd13e4e14a8c80b7c9d475feb58c258babc0 But I think 18.04 will get that fix soon as part of the proposed update: https://launchpad.net/ubuntu/+source/mutter/3.28.3+git20190124-0ubuntu18.04.1 Gnome 3.30 (Ubuntu 18.10) onward already contains that fix. So could you please test one of: * Ubuntu 18.10 * Ubuntu 19.04 * Ubuntu 18.04 with proposed updates enabled and tell us the version of the 'mutter' package you are testing. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1817620 Title: High cpu usage on alt-tab-ing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1817620/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
