The system is stuttering due to browser load
I have the most severe stutters when, for example, I'm watching a jam compilation on YouTube with music.
When the video changes in the background, a severe stutter occurs.
Or, for example, when I close the tab with this music, the system simply feels like some kind of denial of service for like 2 seconds, and then everything returns to normal.
That is, if you're listening to a jam compilation on youtube, then it turns out that every 5 minutes or so there is a hellish lag.
It's annoying because if you type something at this very moment, instead of "word" you might get "worrrrrrrrrrrrrrrrrrrrrrrrd"
PC - i78700 gtx1080 16gb
GNOME Wayland
$ uname -r
6.18.2-arch2-1I restarted the system and now this problem is gone, But when using the system for a long time without restarting, the problem recurs

Re: The system is stuttering due to browser load
its looks like scheduling, i think. After a reboot, everything seems fine
But I think this will appear again

Restarting GDM (Gnome Desktop Manager) got rid of the stutters.
But it is not clear why they arise in the first place
I noticed that stutters occur at the very moment the video is launched in the browser and after that everything returns to normal.

Re: The system is stuttering due to browser load
A snapshot of the interrupts doesn't say much - you want to figure which value increases rapidly (if any)
Restarting GDM (Gnome Desktop Manager) got rid of the stutters.
But that also implies a complete restart of the desktop session.
The latter by itself isn't sufficient? You /have/ to restart GDM?

Re: The system is stuttering due to browser load
Also experiencing this. It seems to correspond to short bursts of 100% CPU from the gnome-shell process. It persists even with all applications closed and all extensions disabled.
Restarting gnome-shell (that is, logging out and logging back in) seems to resolve the problem.
