在 M-x, C-h-f, C-h-v 中使用 ivy-posframe-avy, avy-keys 会显示在每行候选项的左端，但是一闪而过。但是继续按相应的 avy-keys，仍然是有效果的。
另外在 swiper 中使用 ivy-posframe-swiper-avy, avy-keys 显示在被搜索的 buffer 中，而不是在 ivy-posframe frame 中。
我在以下的配置中测试会出现上述问题
(use-package counsel
:ensure t
:diminish counsel-mode
:after ivy
:bind (("M-r" . counsel-register)
("M-y" . counsel-yank-pop)
("C-x d" . counsel-dired)
:map ivy-minibuffer-map ("M-y" . ivy-next-line))
:init
(counsel-mode)
:config
(setq counsel-dired-listing-switches "-alhtgG"))
(use-package ivy
:ensure t
:diminish (ivy-mode)
:bind (("C-x b" . ivy-switch-buffer))
:init
(ivy-mode)
:config
(setq ivy-use-virtual-buffers t)
(setq ivy-count-format "%d/%d ")
(setq ivy-display-style 'fancy)
(setq ivy-initial-inputs-alist '((counsel-minor . "^+")
(counsel-package . "^+")
(counsel-org-capture . "^")
(counsel-M-x . "^")
(counsel-describe-symbol . "^")
(org-refile . "^")
(org-agenda-refile . "^")
(org-capture-refile . "^")
(Man-completion-table . "^")
(woman . "^")
(ryb-register . "^")
(counsel-register . "^"))))
(use-package ivy-avy
:ensure t)
(use-package swiper
:ensure t
:bind (("C-s" . swiper)
("M-x" . counsel-M-x)
("C-t" . isearch-forward)
("C-x C-f" . counsel-find-file))
:config
(progn
(setq ivy-use-virtual-buffers t)
;; (setq ivy-display-style 'fancy)
(define-key read-expression-map (kbd "C-r") 'counsel-expression-history)))
(use-package avy
:ensure t
:bind (("M-s" . avy-goto-word-1)
("M-S" . avy-goto-char))
:config
(setq avy-all-windows nil)
(setq avy-line-insert-style 'below)
(setq avy-orders-alist '((avy-goto-char . avy-order-closest)
(avy-goto-word-1 . avy-order-closest))))
(use-package ivy-posframe
:ensure t
:diminish ivy-posframe-mode
:config
(setq ivy-posframe-display-functions-alist
'((t . ivy-posframe-display-at-frame-bottom-left)))
(setq ivy-posframe-parameters
'((left-fringe . 8)
(right-fringe . 8)))
(setq ivy-posframe-border-width 2)
:init (ivy-posframe-mode 1))
请教大家如何解决这两个问题？
是的，我这边这个效果就是一闪而过。我在 archlinux 和 windows 上都试过，结果都是一闪而过 
非常感谢开发者的回复 
我用如下方式做了测试，结果仍是一闪而过
（限于我有限的 emacs 知识，如有不合适的，请指正）：
- 在终端中用
emacs -q 启动
- 对如下的文件用了
eval-buffer
(tool-bar-mode 0)
(scroll-bar-mode 0)
(require 'package)
(setq package-enable-at-startup nil)
(package-initialize)
;; Bootstrap `use-package'
(unless (package-installed-p 'use-package)
(package-refresh-contents)
(package-install 'use-package))
;; ------------------------
(require 'ivy-avy)
(require 'swiper)
(global-set-key "\C-s" 'swiper)
(global-set-key (kbd "M-x") 'counsel-M-x)
(global-set-key (kbd "C-x C-f") 'counsel-find-file)
(require 'ivy-posframe)
(ivy-posframe-mode 1)
这个问题可能和 ivy-posframe randomly blink #21 有关。
加载 kongds 的如下代码后，ivy-posframe-avy 一闪而过的问题就解决了。
(defvar ivy-posframe--first-show t)
(defun ivy-posframe-cleanup ()
"Cleanup ivy's posframe."
(setq ivy-posframe--first-show t)
(when (posframe-workable-p)
(posframe-hide ivy-posframe-buffer)))
(defun ivy-posframe--display (str &optional poshandler)
"Show STR in ivy's posframe with POSHANDLER."
(if (not (posframe-workable-p))
(ivy-display-function-fallback str)
(with-ivy-window
(if (not ivy-posframe--first-show)
(with-current-buffer ivy-posframe-buffer
(erase-buffer)
(insert str))
(setq ivy-posframe--first-show nil)
(apply #'posframe-show
ivy-posframe-buffer
:font ivy-posframe-font
:string str
:position (point)
:poshandler poshandler
:background-color (face-attribute 'ivy-posframe :background nil t)
:foreground-color (face-attribute 'ivy-posframe :foreground nil t)
:internal-border-width ivy-posframe-border-width
:internal-border-color (face-attribute 'ivy-posframe-border :background nil t)
:override-parameters ivy-posframe-parameters
(funcall ivy-posframe-size-function)))
(ivy-posframe--add-prompt 'ignore)))
(with-current-buffer ivy-posframe-buffer
(setq-local truncate-lines ivy-truncate-lines)))
我比对了上述 kongds 的代码和原始的 ivy-posframe--display 代码，主要起作用的是下面这行：
:hidehandler #'ivy-posframe-hidehandler
进一步，修改 ivy-posframe-avy 如下
(defun ivy-posframe-avy ()
"Ivy-posframe's `ivy-avy'."
(interactive)
(let ((avy-pre-action #'ignore))
(message "buffer-name-outside is %s" (buffer-name)) ;; Line 1
(with-selected-window (ivy-posframe--window)
(message "buffer-name-inside is %s" (buffer-name)) ;; Line 2
(ivy-avy))))
并在 M-x 中用 ivy-posframe-avy (按 C-')，返回如下
buffer-name-outside is *Minibuf-1* ;; Line 1
buffer-name-inside is *ivy-posframe-buffer* ;; Line 2
在测试过程中，ivy-posframe-hidehandler 一直在执行，从而在 ivy-posframe-avy 的 with-selected-window (ivy-posframe--window) 后，似乎有个窗口短暂的变换过程导致 ivy-posframe-hidehandler 返回 t
应该不对效率有多大影响，毕竟是 timer 运行的函数。
