But I struggle to say if it's been fixed or is it because hw I work on got more powerful.Maybe we should just assume it has been fixed then? It seems to me that it's hard to debug without an example file which exhibits this behaviour.As a reporter, I agree. Should anyone stumble upon this again, I think they should create a new report. FTR: the Emacs version I'm currently using is a build from git dated by 13.09.2019
Oh, I figured there's one thing in my current setup I should explicitly mention! It is this: ;; run garbage collection only when idle (setq gc-cons-threshold most-positive-fixnum) (run-with-idle-timer 2 t (lambda () (garbage-collect))) Looking at the original stack, I see GC was taking 14%, so it may or may not be relevant.
