It's a bug! I've been noticing the same thing since I switched to Emacs 29.2,
but also figured it's probably user error. Since I don't often create a second
frame, it didn't bother me enough to investigate, but if it's happening to
others as well, it's probably a bug.

Yes, that's my setup as well.

Yup. I actually never had any window size settings in my default-frame-alist,
but up until Emacs 28, the default width/height was fine. And if I start Emacs
by calling emacsclient, the frame that pops up is still that same size. But
creating a new frame with `C-x 5 2` produces a much smaller frame. Unusably
small, in fact.

Indeed. Note that if you clone a frame with the `fullscreen` frame parameter set
(to `maximized` in my case), cloning the frame yields another maximised frame.

Emacs 29.2. I don't recall having this problem with Emacs 28, though I can't be
entirely sure.

I don't think there is anything you're doing wrong.

Stefan Monnier suggested you report it as a bug, which is probably a good idea.
