Hello ELi,

I don't see any message on stderr, but a bunch of messages:
"Invalid image size (see ‘max-image-size’)" in the *Messages* buffer,
probably related to the display of an invalid image (empty square)
in the *scratch* buffer. Also, the result of image-size is not the
expected image size (22x22 px in example). I attached a screenshot.

Thanks
