Thanks for testing, I'm therefore closing this bug.

I encountered this issue when I'm editing some code using flycheck-mode
and evil-mode: after flycheck-mode added an error region at the end of
the line, press <down> on this line should forward two lines instead of
one.

Here's the recipe to reproduce it using 'emacs -Q':


    (with-current-buffer (get-buffer-create "test")
      (setq truncate-lines t
            line-move-visual nil)
      (erase-buffer)
      (insert (make-string 1000 ?x) "\nHELLO\nWORLD\n")
      (let ((ov (make-overlay 1001 1002)))
        (overlay-put ov 'before-string
                     (propertize "!" 'display '(left-fringe right-arrow error))))
      (beginning-of-buffer)
      (switch-to-buffer (current-buffer)))

After executing the code, press <down>, the cursor would move to line 3;
but I think the expected behavior is that the cursor would move to line 2.

Thanks!
