To answer your first question: I'm testing on a freshly booted system with no applications running.
Regarding extensions: After I disable the Desktop Icons NG extension (appears to be one of the built-ins), peak CPU usage for gnome-shell goes from ~55% to ~35% when moving over an empty desktop. When moving over an application such as gnome-terminal, CPU usage for gnome-shell increases to ~60% both with and without this extension (and also gnome-terminal itself consumes about 25%). Besides that I have Ubuntu Dock and Ubuntu AppIndicators - disabling them didn't affect CPU usage. evtest output attached. ** Attachment added: "evtest.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+attachment/5749814/+files/evtest.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2051383 Title: gnome-shell high CPU utilization when moving a high frequency mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
