As part of this replay, it outputs "C-x", then "C-x 5", then "C-x 5-" > to the echo area, which causes the "5-" to look like it is flickering. This is deliberate, the code is explicitly written to replay the key sequence. For more about this, see http://lists.gnu.org/archive/html/emacs-devel/2018-09/msg00906.html
