This is what made me suspect jit-lock, because of the 5 sec idle timer=20= followed by jumping at 0.5 secs intervals. Here's my timer list: 0.37 0.01 blink-cursor-timer-function 6.59 - undo-auto--boundary-timer 47.03 1.00 display-time-event-handler * 0.00 t show-paren-function * 0.50 t #f(compiled-function () # = [jit-lock--antiblink-grace-timer jit-lock-context-fontify]) * 0.50 :repeat blink-cursor-start * 1.00 t which-key--update * 5.00 t jit-lock-stealth-fontify Could the sporadic nature hint at the byte-compiled function that calls=20= jit-lock-context-fontify? (Also I see jit-lock-antiblink-grace is new=20 in 27.) Of course there's also which-key, so I've turned that off for the time being.
