But that example is a single event and does not cause glitch or
flickering.

Emacs usually does not move the cursor by writing newline characters
because it feels like it.  And it does not do that frequently.

If I do not do anything, Emacs will not do anything (except updating
clock in the mode-line perhaps, which is outside the buffer with the
image).

Now after that single event, the image should be redrawn but that's it.
