Hello everyone,

The mode visual-wrap-prefix-mode sometimes causes images to be displayed
incorrectly in emacs (in a mosaic-like way).

To this mail are attached screenshots of the problem and the image file
used in the screenshots which is from wikipedia:
- https://fr.wikipedia.org/wiki/Olcades
- https://upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Iberia_300BC-fr.svg/langfr-873px-Iberia_300BC-fr.svg.png

Note that the error does not occur with all images, but I am not able to
identify which characteristic of an image makes the problem appear.
Still, I have encountered the problem with multiple image files.

In emacs -Q:
- enable global-visual-wrap-prefix-mode,
- open the attached image.

All the best,
Gautier.
