        I try to use lualatex on the attached code in an attempt to
        avoid xelatex
        <br>
        since it requires the NOSAFER option in it's configuration or
        commandline.
        <br>
        <br>
        But lualatex produces errors. So I would like to ask if I need
        some package which I do not know of
        <br>
        or it is bug somewhere. The attached pdf is from xelatex which
        compiles the file fine. (I am on texlive2021)

      there are some bugs in pst-geometrictools. Use the attached
      version and it
      <br>
      should work with lualatex. For transparency you need the first two
      lines
      <br>
      of the follwing code.
