As my last email is rejected by mailing list moder.

So I uploaded attachment files to other servers. And post email again.

I checked emacs-devel mailing list archive, found my email is not sent
successfully from mu4e client. So send on gmail again.

At first, let me show the problem I meet. Here is a recorded video
"simplescreenrecord*.mkv". I tested
this with Minimal Emacs Config. You can see, the original line height is
failed after I split window (which
window width is decreased).

I also attached the material "org-agenda.org" of reproducing the
environment.

I have a configuration which add colored blocks on Org Agenda headlines.
Here is
my Minimal Emacs Config "emacs-minimal.el"
