The following slight variation of the previously filed issue #54862 also
yields a wrong result of window-text-pixel-size.
To reproduce the issue, please invoke Emacs with:
$ emacs -Q
and then evaluate the following form:
(let ((width 20))
(= width (let* ((height (line-pixel-height))
(data (with-temp-buffer
(insert (format "P1\n%s %s\n" width height))
(dotimes (_ height)
(insert (make-string width ?1) "\n"))
(buffer-string))))
(insert "\n")
(insert-image `(image :type pbm
:data ,"P1\n1 10\n1111111111"
:ascent center) "t")
(let ((from (point)))
(insert-image `(image :type pbm :data ,data :ascent center) "t")
(car (window-text-pixel-size nil from (point)))))))
The expected result, obtained for example in Emacs 26.1, is: t.
With Emacs 30.0.50, I instead unexpectedly get: nil.
If possible, could you please restore the previous behaviour?
Thank you and all the best,
Markus

Thanks, should be fixed now on the emacs-29 release branch.

Thanks for testing, I'm therefore closing this bug.
