I'm just starting to customize emacs on RHEL8, the entirety of the .emacs file is this:
(setq default-frame-alist '((width . 80) (height . 40) (menu-bar-lines . 1)))
When starting Emacs this sets the first frame size appropriately. However, when I create a new frame (C-x 5 2) the new frame does not use these values (it is tiny instead). How do I get subsequent frames to respect the size?
I don't see that, when I start Emacs with emacs -Q, in any official Emacs release (up through 27.2, which is the most recent release).
Try -Q instead of -q, to see if the problem is with your site-lisp.el.
State what version of Emacs you're using (emacs-version) and on what platform.
Check that C-x 5 2 is bound to make-frame-command. If it's not, and you're using emacs -Q, then you're likely using some prelease version of Emacs, where the behavior of that key has changed (a backward-incompatible change).
Consider filing an Emacs bug: M-x report-emacs-bug.
