Thanks for the bug report. Since we find so many bugs are caused by extensions, that's the first thing we need to look at. And you have a lot:
desktop-icons@csoriano', 'ubuntu-appindicat...@ubuntu.com', 'ubuntu- d...@ubuntu.com', 'walkpa...@walkpaper.blinkbp.github.com', 'apps-menu @gnome-shell-extensions.gcampax.github.com', 'places-menu@gnome-shell- extensions.gcampax.github.com', 'screenshot-window-sizer@gnome-shell- extensions.gcampax.github.com', 'user-theme@gnome-shell- extensions.gcampax.github.com', 'window-list@gnome-shell- extensions.gcampax.github.com', 'workspace-indicator@gnome-shell- extensions.gcampax.github.com' Please uninstall or disable all but the first three in the Extensions app and then log out and log in again. Does the problem still happen? ** Tags added: performance ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903446 Title: the process gnome-shell stay active for ever, and take 6-7 perc. of resorce, without apparent reason To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1903446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
