Confirmed.  An important observation is, that you are plotting with
"gnuplot".  For "fltk" and "qt" I do not see this DEBUG message.  Is
there a particular reason, why you want to use "gnuplot"?

The message is printed in


C:\Octave\Octave-5.2.0\mingw64\share\octave\5.2.0\m\plot\util\private\__gnuplot_print__.m
(line 201)

with the gnuplot-pipeline:

'C:\Octave\OCTAVE~1.0\mingw64\bin\gs.exe -dQUIET -dNOPAUSE -dBATCH
-dSAFER -dAutoRotatePages=/None -sDEVICE=png16m -dLanguageLevel=2
-dTextAlphaBits=4 -dGraphicsAlphaBits=1 -r72x72 -dEPSCrop
-sOutputFile="temp.png"
C:\Users\siko1056\AppData\Local\Temp\oct-tdNSWy.eps & del
C:\Users\siko1056\AppData\Local\Temp\oct-tdNSWy.eps'

Thus it seems indeed to be a ghostscript problem.
