First, check if those are not add-ons by running a clean profile. Mere
belief that they’re not the culprit is not evidence.
If the behaviour continues in a clean profile, check load during those
stalls — e.g. in `htop`, which shows a nice load graph. Possibly
If that doesn’t explain the problem, check if dmesg contains any
errors that correlate with your issue. That’s unlikely, but not impossible.
Also see if you do have enough of RAM and no swapping occurs. That
shouldn’t be a concern on any modern computer, but the symptom is
similar and, since I have no specific ideas, everything’s worth checking.
