>     Hi there,
>     
>     I am not a skilled Emacs user. I mainly use Emacs as a front end for
>     Maxima with the help of imaxima. imaxima converts Maxima output into
>     PNG image, which are then displayed in Emacs. I am using Windows 10.
>     
>     It works fine on Emacs 28.2, when I type an _expression_, e.g. q^2
>     = 1; and return, Emacs 28.2 immediately displays the resulting PNG
>     image.
>     
>     
>     If I use Emacs 29.1, however, all I get after returning is an empty
>     square. And if I type another _expression_ and return, a blank square
>     appears. At the same time, the first empty square was replaced by a
>     PNG image of the first _expression_. That's weird.
