Resizing mini-fame doesn't work in 29.1?

[zck]

I just upgraded to Emacs 29.1. Mini-frame works on its own, but when combined with Vertico (which also works on its own), it doesn't work anymore.

A screenshot is attached.

Reproduction instructions:

1. Install Emacs 29.1
2. Install vertico

(package-install-file "~/.emacs.d/elpa/vertico-1.4/vertico.el")
(vertico-mode 1)

4. Test vertico with C-x C-f. It works properly; that is, I see vertical completions.
5. Disable vertico

(vertico-mode -1)

6. Install mini-frame

(package-install-file "~/.emacs.d/elpa/mini-frame-20220627.2041/mini-frame.el")
(mini-frame-mode 1)

7. Test mini-frame with C-x C-f. It works properly; that is, I see the single option at the top of the frame.
8. Enable vertico mode again.

(vertico-mode 1)

9. Test with C-x C-f and see that it behaves weirdly. The look is as the screenshot above, and nothing is able to be selected. Pressing C-g several times in a row exits out of it, ususally.

Works for me. Just compiled recent Emacs 29 version and then in emacs -Q

1. M-x package-initialize
2. M-x vertico-mode
3. M-x mini-frame-mode
4. M-x

GNU Emacs 29.1.50 (build 1, aarch64-apple-darwin22.5.0, NS appkit-2299.60 Version 13.4.1 (c) (Build 22F770820d))

@zck I've checked latest Emacs-mac build and see the same issue. But I can see the same behaviour without any packages just by using separate mini-buffer frame with resize-mini-frames turned on.

Can you please check if Emacs is working for you if you launch it like this:

emacs -Q --eval "(setq default-frame-alist '((minibuffer . nil)))" --eval "(setq resize-mini-frames t)"

Weird! When I do that, I get two windows open.

When I run C-x b, it looks like this:

It is ok that two windows are created because we told Emacs that default frame should not contain mini-buffer, so separate window is created.

What is not ok is that I can not use Emacs in this case. Emacs just hangs when pressing C-x C-f to open some file.

Can you change the buffer after C-x b or your Emacs is hanging too?

[zck]

My emacs hangs as well.

Can you please report this issue to Emacs bugs tracker?

Hi, using this command (omitting the second occurrence of --eval seems to fix the hanging:

emacs -Q --eval "(setq default-frame-alist '((minibuffer . nil))) (setq resize-mini-frames t)"

Hi, using this command (omitting the second occurrence of --eval seems to fix the hanging:

emacs -Q --eval "(setq default-frame-alist '((minibuffer . nil))) (setq resize-mini-frames t)"

The hanging is fixed because this way the resize-mini-frames variable is not set. You can check the variable value by C-h v resize-mini-frames.

You're absolutely right, can't believe I didn't see that one.
