Could you describe in more detail what happened to cause the text at
the end of the buffer be displayed instead of the image?  Is it that
the buffer included an image and also some text, and that buffer was
scrolled such that the image went out of view and the text came into
view?  Or was it some other scenario, like maybe switching buffers in
the window?

Andreas, perhaps you also could give such details about your case?

I think I see the code that could be the culprit, but I need to
understand better how the new display replaced the old one, to dig
deeper.

TIA
