git-gutter在终端下的emacs26有问题，改动一行后，上下移动光标，文本的内容不停的往后面移动，就像在所有行的前面不停的添加空格一样，但是在emacs25下面就没问题，下面有我的截图和我的git-gutter的配置，有人知道这咋解决么？
(use-package git-gutter
:ensure t
:config
;; If you enable global minor mode
(global-git-gutter-mode t)
;; If you would like to use git-gutter.el and linum-mode
(git-gutter:linum-setup)
;; Use for 'Git'(`git`), 'Mercurial'(`hg`), 'Bazaar'(`bzr`), and 'Subversion'(`svn`) projects
;; (custom-set-variables '(git-gutter:handled-backends '(git hg bzr svn)))
(custom-set-variables '(git-gutter:handled-backends '(git svn)))
;; inactivate git-gutter-mode in asm-mode and image-mode
(custom-set-variables '(git-gutter:disabled-modes '(asm-mode image-mode)))
;; Hide gutter when there are no changes if git-gutter:hide-gutter is non-nil. (Default is nil)
(custom-set-variables '(git-gutter:hide-gutter t))
;; diff information is updated at hooks in git-gutter:update-hooks.
(add-to-list 'git-gutter:update-hooks 'focus-in-hook)
;; diff information is updated after command in git-gutter:update-commands executed.
(add-to-list 'git-gutter:update-commands 'other-window)
;; (custom-set-variables
;; '(git-gutter:modified-sign "~") ;; two space
;; '(git-gutter:added-sign "++") ;; multiple character is OK
;; '(git-gutter:deleted-sign "--"))
;; (set-face-background 'git-gutter:modified "purple") ;; background color
;; (set-face-foreground 'git-gutter:added "green")
;; (set-face-foreground 'git-gutter:deleted "red")
