This is probably an issue with what version of the gtk library is used.
gtk2 provided a "invert the color" pen that would always draw white on a dark
background or black on a light background.
For some reason gtk3 does not support that option.  This was bug #2523
      https://sourceforge.net/p/gnuplot/bugs/2523/

It was supposedly fixed in version 5.4.4
  commit 10152d7a736da4ab289c12d532cae50683a8306b
  Date:   Thu May 5 16:56:06 2022 -0700
    wxt: Flip color of zoombox / rubber band / ruler on dark background
    Bug #2523

Maybe that fix did not work for Windows 10?
Or maybe for some reason on your machine gnuplot thinks the
terminal background is dark even though in fact it is white?
