Hi Bernt, thanks for the report. I tried your example and it works for me:
It is on a Win10 box but with TeXlive installed and not MikTeX. Preview uses in this case `rungs.exe' (TeXlive's counterpart of mgs). I've set the variable `preview-gs-command' to gswin64c.exe and indeed it didn't work as well. My current guess is that running `pdf2dsc ...' somehow fails. TeXlive ships a small executable called pdf2dsc.exe which seems to do the job. Does MikTeX comes with such a thing? Best, Arash
