At this stage, that depends how severe the problem is (not very IMO),
and how safe any fix is. At first sight, using ACTION = t with
display-buffer doesn't seem too safe to me. That code's been the way it
is for many years, so a bisection to find the cause might be
informative.

BTW minimal example is

echo "Monday foo" > ~/diary
emacs -Q --eval '(setq calendar-view-diary-initially-flag t)' \
  --eval '(progn (diary) (calendar))'


At some point all this stuff should be rewritten to use modern methods
of displaying buffers, but not now, obviously.
