Then either you truncate the candidate's (i.e., don't show all of it),
or your code isn't working properly.

Not sure I can parse this properly. What exactly isn't "kicking in"?

I think whoever truncates the display is the same as the client.
Unless I misunderstand what you mean by "truncate".

There are ways. They aren't necessarily easy, but if your application
does care about not everything being visible in a window, the
application must do something about it, because the "normal" Emacs
display doesn't treat partial display of a buffer as something
special, since that is what happens all the time in Emacs.

We have window-text-pixel-size for that.

Yes.

Not sure what should be canonical here. AFAIU, just using
window-text-pixel-size and comparing with the window dimensions is all
that's needed.
