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). However, when redisplay-dont-pause is nil, sometimes it stops updating for a bit but with scroll bar still moving, only eventually updating. Maybe that was previously masked.
