Strange flicker when decorating docblocks

[sergeyklay]

There is an annoying flicker when php-mode decorates docblock I'd like avoid to. Is there any fix/workaround for this?

Take a look at class' docblock (array word) as well as method' docblock.

Used config:

(defun my|common-php-hook ()
  "The hook to configure `php-mode'."
  (eval-when-compile (require 'flycheck nil t))
  (when (file-exists-p "~/.composer/vendor/bin/phpcs")
    (setq-local flycheck-php-phpcs-executable "~/.composer/vendor/bin/phpcs"))

  ;; Coding style
  (setq-local flycheck-phpcs-standard "PSR2")
  (setq-local php-project-coding-style 'psr2)

  ;; Fill, indents
  (setq-local fill-column 120)
  (setq-local indent-tabs-mode nil)

  (when (eq 0 (buffer-size))
    (insert "<?php\n\n")))

(use-package phpt-mode
  :defer t
  :init
  (add-hook 'phpt-mode-hook #'(lambda () (flycheck-mode -1))))

(use-package php-mode
  :defer t
  :hook
  ((php-mode . subword-mode)
   (php-mode . flycheck-mode)
   (php-mode . yas-minor-mode)
   (php-mode . my|common-php-hook)
   (php-mode . php-enable-symfony2-coding-style))
  :config
  (setq php-mode-coding-style 'psr2)
  (when (file-directory-p "/usr/local/share/php/doc/html")
    (setq php-manual-path "/usr/local/share/php/doc/html"))
  :bind
  (:map php-mode-map
        ("C-c C--" . #'php-current-class)
        ("C-c C-=" . #'php-current-namespace)))
