** Description changed: 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 + --- + ProblemType: Bug + ApportVersion: 2.20.11-0ubuntu27.9 + Architecture: amd64 + CasperMD5CheckResult: skip + CurrentDesktop: ubuntu:GNOME + DisplayManager: gdm3 + DistroRelease: Ubuntu 20.04 + InstallationDate: Installed on 2018-08-18 (794 days ago) + InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) + NonfreeKernelModules: lkp_Ubuntu_5_4_0_48_52_generic_72 nvidia_modeset nvidia + Package: gnome-shell 3.36.4-1ubuntu1~20.04.2 + PackageArchitecture: amd64 + ProcVersionSignature: Ubuntu 5.4.0-48.52-generic 5.4.60 + RelatedPackageVersions: mutter-common 3.36.6-1ubuntu0.20.04.2 + Tags: focal + Uname: Linux 5.4.0-48-generic x86_64 + UpgradeStatus: Upgraded to focal on 2020-10-04 (16 days ago) + UserGroups: adm cdrom dialout dip docker kvm lpadmin plugdev sambashare sudo vboxusers + _MarkForUpload: True ** Attachment added: "Dependencies.txt" https://bugs.launchpad.net/bugs/1900760/+attachment/5425028/+files/Dependencies.txt -- 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/1900760 Title: gnome-shell very high %CPU usage while moving mouse on Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1900760/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
