I encounter the same issue from time to time. Almost consistently reproducible when I update the kernel and the VirtualBox driver needs to be recompiled (and there's no cap for that process that it should use max X% of CPU).

As pipewire is within the user session I would assume higher system load would induce some latency and cause the jitterness.

But in the end I'm just making assumptions, and correlating.

PipeWire, just like PulseAudio, uses rtkit if available. Your distro may have made it an optional dependency, so you may not have it installed.

This sounds about correct. I had a similar hunch, but I noticed it correlating to high memory instead (could be just a symptom, perhaps it was doing more swapping?). I increased my swap partition, which made it happen less often. It could be very well be the CPU.

Distros should really be setting niceness levels on more processes by default, especially background software updates. And anything audio-related really needs to be at a realtime priority.
