Original Font issue.pdf and outputed Font issue.jpg

When I try to render the "Font issue.pdf" attached, the Ghostscript outputs the text repeated several times staked vertically. See "Font issue.jpg".

The command line is:
gswin32c.exe -dSAFER -dBATCH -dNOPAUSE -sDEVICE=jpeg -r150 -dTextAlphaBits=4 -sOutputFile="Font issue.jpg" "Font issue.pdf"

But if I remove the TextAlphaBits parameters, the file is rendered fine.

Hi, Chris. Thank you for looking in! Yes, it seems like the same issue. But my sample file is much simpler, so may be it'll be easier to trace down the bug using my PDF.

Yes, hopefully the simpler file will help. As mentioned in the other bug, it looks like an anti-aliasing problem, rather than a font problem, but I may have a proper look when I have time.

Chris

(For the record, ignore comment #1 - I've checked with Chris and that was a mistake).
