Thanks, it is fixed .

But  the bug of  "disappearing prompt and entered text problem" came back again, when I  (setq max-mini-window-height 10)  

```

(setq icomplete-show-matches-on-no-input t)
(icomplete-mode 1)
(setq icomplete-format 'vertical)

(defface vmacs-minibuffer-font
 `((t :inherit default :height 1.3))
 "The default font for minibuffer buffer.
Monospaced font whihc is fixed idth and height is recommended."
 :group 'minibuffer)

(defun vmacs-minibuffer-hook()
 (set (make-local-variable 'buffer-face-mode-face) 'vmacs-minibuffer-font)
 (buffer-face-mode t))

(add-hook 'minibuffer-setup-hook #'vmacs-minibuffer-hook)

(setq max-mini-window-height 10)   ;; add  this line
```
