bug#68452: w32-use-native-image-API makes weird behavior

[Jinsong Zhao]

    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.
    
    
    I saw the following messages in the *Messages*
    buffer:
    
    
    Processing Maxima output...done
    
    Unable to load image (image :type png :file
    c:/Users/Jinso/AppData/Local/Temp/imaximatU5Y9B/1 :scale
    1.001595744680851 :ascent center :mask (heuristic (color-values
    imaxima-bg-color)) :transform-smoothing t) [35 times]
    
    Process imaxima finished
    
    
    After (setq w32-use-native-image-API nil), imaxima has the same
    behaviour on Emacs 28.2 and 29.1.
    
    Best,
    Jinsong
