Thanks for the bug report. The two most likely causes of this problem are:
* Shell extensions * Chrome tabs so you should check each of those separately... Please delete locally installed shell extensions by running: cd ~/.local/share/gnome-shell/ rm -rf extensions and then log in again. Please also try just closing Chrome when it happens. Does the system recover? After you have closed Chrome and deleted all local shell extensions, if the problem persists then next please provide output from 'top' and 'ps' while the problem is happening to show the top CPU and memory users. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- 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/2004063 Title: mouse pointer becomes laggy after some time and progressively gets worse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2004063/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
