Public bug reported: After upgrade from 18.04 to 20.04 I discovered that gnome-shell occasionally starts eating up unreasonably large CPU %. After some head scratching why on earth i thappens, it was clear that moving my mouse energetically I can get it as close to 100% as I want.
If this is relevant, the mouse model is Corsair Harpoon wireless BT. I am reading some speculation that the cause of the problem is high polling rate for mouse location (?). It is suggested in this bug entry (https://bugs.launchpad.net/bugs/1848951) that this issue is fixed on late march. But this is october and I still experience this problem on an updated PC. gnome-shell version on my system: 3.36.4-1ubuntu1~20.04.2 ** Affects: gnome-shell (Ubuntu) Importance: Undecided Status: New -- 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: New Bug description: After upgrade from 18.04 to 20.04 I discovered that gnome-shell occasionally starts eating up unreasonably large CPU %.
