window.c: Still recentering sometimes.
Does the problem go away if you disable font-lock-mode?
I could not reproduce today without font-lock-mode on two complete
scrollthroughs (one with redisplay-dont-pause and one without).
font-lock-mode on:
redisplay-dont-pause nil (that's nil):
I counted about 114 visible recenters on one complete scrollthrough
(N.B. definitely recenters i.e. cursor restarting from the middle, not
just update lags),
redisplay-dont-pause t (that's t):
No visible recenters on one complete scrollthough.
I guess you've fixed _something_, just not the issue Lennart is talking
about: HELLO is definitely recentering less often than it was (making
the window narrower so that lines wrap makes it happen more repeatably).
Again, does it happen if you disable font-lock-mode and
bidi-display-reordering?
Yes (font-lock-mode doesn't appear to do anything visible at a glance on
HELLO, but I turned it off anyway).
redisplay-dont-pause nil (that's nil):
Only visibly once in 20 whole buffer scrollthroughs (HELLO being a lot
shorter than window.c...), though with at least one of those update lags
every time.
redisplay-dont-pause t (that's t):
11 times in 20 whole buffer scrollthroughs.
Note there were still some wrapped lines during that test, which I have
some difficulty eliminating with emacs -Q at present with typical
window sizes owing to #6471.
