I cannot reproduce this here.  I get the expected result.  I also get
this result from create-image:

 (image :type png :file "two_key_system_2x.png" :scale 1 :transform-smoothing t)


Is this in "emacs -Q"?  If so, what version of libpng do you have
installed there?  And what happens if you start Emacs like this:

  emacs -Q --eval "(setq w32-use-native-image-API t)"

Thanks.
