Subject: bug#69140: 30.0.50; [elpa/vertico] Emacs with vertico-mode freezes if font is too big
Date: Thu, 15 Feb 2024 14:23:28 +0300

Hi,

Vertico version 1.7, version 1.3 has also been tested, is incompatible
with the changes made by the commit -
caea0c1649d1df96b811c1388fde396e66bc356b. This commit was found via
git bisect.

To reproduce:
1. Run emacs -Q
2. M-x load-library vertico RET
3. M-x vertico-mode RET
4. Set a large font, the following is suitable for my 13 inch monitor:
(set-face-attribute 'default nil :family "monospace" :height 440)
5. Call M-x
Emacs should freeze, sometimes you can unfreeze it with a few presses
of C-g
