OK it looks like the increase in CPU in activities overview is just expected. Mutter/Gnome Shell is fairly inefficient to start with so switching to a mode where it has to render more widgets and more detail of course incurs higher CPU.
I think a holistic approach is required. Not just fixing this bug, but to reduce CPU usage in all scenarios such that a 60% increase doesn't hurt so much. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1757088 Title: Activities overview causes increased CPU in Wayland & Xorg Status in gnome-shell package in Ubuntu: In Progress Status in mutter package in Ubuntu: In Progress Bug description: gnome-shell CPU usage increases about another 60% when in activities overview To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1757088/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
