I can't seem to reproduce the problem, although I can see that Firefox uses high CPU for a lot of things...
Please: 1. Close clipit. 2. Remove/disable these extensions: 'dash-to-pa...@jderose9.github.com', 'Alt_Tab_Switcher_Popup_Delay_Removal@logswithm...@gmail.com' 3. Reproduce the problem again using some a simpler app, like gedit. Now does gnome-shell show high CPU? ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Tags added: performance -- 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/1894225 Title: Blocked UI and 100% cpu in gnome-shell when selecting text To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1894225/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
