To summarize this long thread, IIUC we have three separate problems:
- in some cases, a minibuffer message with bold text causes
unexpected/unneeded minibuffer resizing. Most likely those fonts
somehow end up with a height just a tiny pixel taller. Maybe we
should change the minibuffer resizing such that it only resizes if the
extra height needed is more than some threshold number of pixels (1
or 2).
- eldoc can cause undesired minibuffer resizing. That can probably still
happen even when we fix the previous problem, depending on face
settings and/or length of eldoc data. So maybe eldoc should come with
a config var for how many max lines of echo-area we're willing to
devote to it. If set to 1 it will prevent any resizing and fix the
OP's problem regardless of whether the previous problem is fixed.
- minibuffer auto-resize can trigger an undesirable recentering.
I'm not sure we can do much about that, tho, since it seems to only
occur in cases where the resizing ends up "eating" the area used by
point, so some scrolling is necessary.
