[Bug 2051383] Re: gnome-shell high CPU utilization when moving mouse cursor
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
[Bug 2051383] Re: gnome-shell high CPU utilization when moving mouse cursor
1. Nope, the log is normal, nothing new is logged when moving the cursor around 2. Razer DeathAdder V2. BTW switching to 60 Hz doesn't seem to change anything. However, switching to an old cheap mouse decreases gnome- shell's CPU usage down to ~10%. 3. Unfortunately that didn't help. I also had this line in my /etc/environment before: MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 Tried both with and without it. -- 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 mouse cursor 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
[Bug 2051383] Re: gnome-shell high CPU utilization when moving mouse cursor
Yes it's normal for the application's CPU usage to go up when it's receiving input events. So that suggests this is just a high frequency problem. * Is your log flooding at all? (journalctl -f) * I can already see you monitor is 144Hz. What model of mouse are you using? * Try adding MUTTER_DEBUG_FORCE_KMS_MODE=simple to /etc/environment and reboot. -- 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 mouse cursor 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

[Bug 2051383] Re: gnome-shell high CPU utilization when moving mouse cursor
I'm sorry, the 20% part was a bit of an overstatement, after observing more I can say it's somewhere between 1% to 5%. I have the following extensions active: - Desktop Icons NG - Ubuntu AppIndicators - Ubuntu Dock Disabling all extensions didn't change anything in my case. Also I've noticed an interesting thing: when moving the cursor, CPU usage goes up for gnome-shell AND for whatever process on top of whose window I"m moving it. For example, if a Text Editor window is active, it goes up for the gedit process. If it helps, below are a few screenshots of "top" taken when I moved my mouse, with Xorg and Wayland for comparison, and a video. -- 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 mouse cursor 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
[Bug 2051383] Re: gnome-shell high CPU utilization when moving mouse cursor
20% when idle is 20% too much. So if we find out what that is then the 60% might become 40%. Do you have any extra gnome-shell extensions active?
