Thanks. And good catch, yes it should be MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 on 22.04
It sounds like the main issue is the input rate of the Razer DeathAdder V2 and gnome-shell's inefficient processing of a high event rate. You should be able to bring it under control with kernel parameter usbhid.mousepoll=2 (or 4 or 8). But this is still a gnome-shell performance bug. ** Summary changed: - gnome-shell high CPU utilization when moving mouse cursor + gnome-shell high CPU utilization when moving a high frequency mouse ** Changed in: gnome-shell (Ubuntu) Status: Incomplete => New -- 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/2051383 Title: gnome-shell high CPU utilization when moving a high frequency mouse To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/2051383/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
