What I did was profile gnome-shell using sysprof, and I found that file /usr/lib/x86_64-linux-gnu/libgobject-2.0.so.0.5502.0 uses 25.06% of CPU time by itself. My guess is that it's called/utilized very frequently. Attached is part of the output that should explain what I'm stating.
Let me know if any more information is necessary. ** Attachment added: "My sysprof findings" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1750197/+attachment/5081778/+files/ProfileOutput_LukeB.txt -- 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/1750197 Title: Activities overview causes heavy CPU spikes in Wayland & Xorg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1750197/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
