Public bug reported: At seemingly random times, gnome-shell uses 100% CPU when moving the mouse cursor over the desktop and top panel. And the frame rate drops to single figures, almost frozen.
I first noticed this in the aggregate menu but the only reliable reproducer I've found is to drag the top panel (like bug 2062538) in a Wayland session. After that, moving the mouse cursor over the desktop wallpaper rapidly makes gnome-shell use 100% CPU when usually it's closer to 10%. The only reliable way I've found of making the bug NOT happen is to: gnome-extensions disable d...@rastersoft.com but that might just be disabling the trigger (dragging the top panel like bug 2062538). So it's possible gnome-shell/mutter is still really to blame. ** Affects: gnome-shell (Ubuntu) Importance: High Status: New ** Affects: gnome-shell-extension-desktop-icons-ng (Ubuntu) Importance: High Status: New ** Affects: mutter (Ubuntu) Importance: High Status: New ** Tags: cursor noble performance ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => High ** Changed in: mutter (Ubuntu) Importance: Undecided => High ** Tags added: cursor -- 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/2063036 Title: gnome-shell 100% CPU when moving the mouse cursor over the desktop and top panel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2063036/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
