I guess you are confused by the mixed-purpose of redisplay-dont-pause ...
it controls whether redisplay is started in sit-for (A), and whether
redisplay is pre-empted once it is started (B).
To repeat, (B) says:
(B) Don't _interrupt_ redisplay once it has started.
And this definitely _is_ (part of) what you get by setting redisplay_dont_pause.
See update_window and update_frame_1 --- in both, force_p is set
if redisplay_dont_pause is set. So setting redisplay_dont_pause will
force a complete redisplay.
Both functions may still call detect_input_pending_ignore_squeezables
if force_p is set (although input_pending is ignored).
The following patch fixes that:
