I've posted this question on stackexchange already, but so far no one can
reproduce it:
https://emacs.stackexchange.com/questions/56207/are-there-different-tooltip-mechanisms
I experience some weird behavior with tooltips:
(progn
(let* ((start (point))
(end (progn (insert "test") (point)))
(ov (make-overlay start end)))
(overlay-put ov 'help-echo
(propertize "xxx" 'display '(image :type jpeg :file
"~/foo.jpg"))))
(display-buffer-other-frame (get-buffer-create "dummy")))
Evaluating this code and moving the mouse pointer over test I get a tooltip
displaying the image file foo.jpg. This is what I expected. The tooltip
appears as a box with a light yellow background color with sharp corners.
But the moment I click into any frame/window the tooltip changes. Now the
tooltip contains no image but the text xxx. Furthermore the tooltip appears
as a transparent black box with rounded corners.
What's going on here? Are their two different tooltip mechanisms with
different capabilities? Can anyone reproduce this behaviour?
If I remove the code lines creating/displaying buffer dummy I do not see
the tooltip with the image (the first one), but only the second one with
the text xxx.
Here are screenshots of the two different tooltips:

I've tested this on Emacs 25.2.2 and 28.0.50, by starting emacs with emacs
-Q and then evaluating the code lines above.
Best regards
Andreas
