It happens on all images which I using text-property to display that is
from Emacs package "org-link-beautify" https://repo.or.cz/org-link-beautify.git.
This package will generate and display a thumbnail image for org-mode
file: link of a video file.

It happens in "emacs -Q" too. Here is the screenshot show the original
image has no horizontal center line. But in Emacs displayed has a line.

Not image file, I use org-mode's command ~org-toggle-inline-images~ to
display image links are also fine has no center-line. But images
displayed in text-property has center-line. *NOTE*: happens on
text-property displayed images.
