Try reproducing the issue after evaluating the code below, perhaps
*trace-output* will have some useful clues.
(load-library "comint.el") ;; Can only trace set-marker from Lisp source.
(defun bug-40323-get-comint-output-marker ()
(list :comint-pmark
(and (markerp comint-last-output-start)
(eq (marker-buffer comint-last-output-start)
(current-buffer))
(process-mark (get-buffer-process (current-buffer))))))
(dolist (fun '(set-marker
comint-send-input
comint-output-filter
comint-adjust-window-point
comint-adjust-point
ansi-color-process-output))
(trace-function fun nil #'bug-40323-get-comint-output-marker))
