1. Bugs like this are usually due to extensions. So first please try disabling any extensions. 2. Please run this command to send us more information about the system: apport-collect 1900760 3. I have actually seen one possible cause for this in recent code changes, but it would only happen after locking and unlocking the machine.

Whoa, there's a lot of info in those apport files. I hope those are relevant. I don't use any fancy Gnome shell extensions. Here's an output of `ls /usr/share/gnome-shell/extensions/`: desktop-icons@csoriano ubuntu-appindicat...@ubuntu.com ubuntu- d...@ubuntu.com That's about it. It's hard to tell right now if the problem surfaces only after locking/unlocking routine. I can confirm that when I was submitting this bug report, the system has indeed went through several sleep and wake-up cycles, and, of course, there was a lock screen every time a wake-up happened. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1900760 Title: gnome-shell very high %CPU usage while moving mouse on Ubuntu 20.04 Status in gnome-shell package in Ubuntu: Incomplete Bug description: After upgrade from 18.04 to 20.04 I discovered that gnome-shell occasionally starts eating up unreasonably large CPU %.

Thanks for all that. It appears the main CPU hog here is bug 1849142, which has a fix coming soon. So to exclude that bug and see if it is the main problem, please: 1. Open the Extensions app 2. Disable 'Ubuntu AppIndicators' 3. Reboot. 4.

[Desktop-packages] [Bug 1900760] Re: gnome-shell very high %CPU usage while moving mouse on Ubuntu 20.04
Did that, now it's much better. Although I was deferring from system updates, reluctant to restart, so this was not a clean test. Moving mouse quickly still makes the Xorg process consume signifficant CPU% (up to 25%), but gnome-shell doesn't get near to the level it used to consume. It's a weird combo, a bug related to Discord app and mouse movement processing, causing the said CPU hog.
