No worries, thank you for clarification.
I ran |C-h v| with |auto-fill-function| as an argument (while in
AUXTeX mode), and I got its value as nil.
Thanks,

Okay, then it looks like a new behavior indeed. It appears that the
\frametitle command was never actually indented, but rather auto-filled,
which had the side effect of indenting it. Now auctex checks whether the
user actually wants to auto-fill before doing so.
I would say that it is a bug and that indentation should be considered
(or done) regardless of auto-filling.
Modifying the behavior in your configuration is a bit awkward, because
(afaik) you have to copy the whole (TeX-add-style-hook "beamer" ...)
form from <auctex installation folder>/style/beamer.el, and make the
change. If you want to go that route, adding (indent-according-to-mode)
before the lines saying ";; This works because \frametitle is a
paragraph command." should work (untested).
Best wishes,
