bug#29711: 25.2; mode-line distortion when using :box on mac os

[Adam Simpson]

1. Paste and then evaluate the following in the *scratch* buffer:
(set-face-attribute 'mode-line nil
                    :foreground "white"
                    :background "red" 
                    :box '(:line-width 5 :color "red"))
(setq-default mode-line-format (list 
              '(:eval mode-line-position)
              mode-line-modes))
2. Open a long file that has thousands of lines. I used ivy.el which is
around 4k lines.

3. Observe the mode-line is "distorted" like so: https://i.imgur.com/qxAsdfm.png

It isn't distorted here, but I'm not on Darwin.  Maybe it's a Darwin
specific issue.  The above PNG image obviously shows display obtained
not in "emacs -Q", so perhaps that too has something to do with the
distortion.

Thanks.

That definitely doesn't happen here.  The :box face causes "Bot" to
slightly move horizontally when the mouse is moved above the mode
line, but here "Bot" moves as a single unit, and no space is left
between B and o.

Doesn't happen here on macOS 10.6.  (For a "long file", I used M-x
find-library simple RET).  Could you please try from emacs -q?

[Adam Simpson]

The below is with emacs -Q.
Also, I left out a step, after step 2 move to the bottom of the document (M - >). The mode line will then become distorted. 

Apologies for the shoddy reporting.

Thanks.  I see "Bot L8984(Emacs-Lisp ElDoc)", as attached, but I don't
see where the problem is.

Actually, no: it's my mistake, I had been testing for the bug on the
emacs-26 branch instead of the 25.2 release.  I also see the bug on
25.2, so it seems like it's been fixed in version 26.  Can you please
try the pretest and verify that this is the case?

FWIW, I cannot see this in 25.2 either, so maybe it was a Darwin

bug#29711: 25.2; mode-line distortion when using :box on mac os

Charles, good catch! It does appear to be fixed in 26 pretest.
Eli, I think it is/was Darwin specific. Not sure what caused it though :(

Hi,

I can replicate this in Emacs 25, but not the master branch, so I
believe it’s fixed. Upgrading to Emacs 26 should fix it.

See bug#23755:
