vterm breaks which-key's minibuffer functionality

[afine]

Load emacs with a configuration file like:

(setq package-archives
      `(("gnu" . "http://elpa.gnu.org/packages/")
	("melpa" . "http://melpa.org/packages/")))

(package-initialize)

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

(use-package which-key
  :config
  (which-key-setup-minibuffer)
  (which-key-mode t))

(use-package vterm
  :config
  (setq vterm-always-compile-module t)
  (setq vterm-kill-buffer-on-exit t))

which-key works fine until a vterm buffer is loaded.

When a vterm buffer is created which-key only shows its output for a moment before it vanishes.

which-key works fine if configured to use a side window

Thanks, @afine. I think that this is due to the fact that vterm resets the point every time there's a change in the window size. This leads to a series of other bugs, so it is a priority to fix it (however, I've been very busy so I couldn't get the chance to look at this in depth yet).
