Description SaGS 2011-07-17 18:59:24 UTC
The following command:

    gswin32c -dTextAlphaBits=4 -r300 "attachment 6537 [details]#.ps"

displays the glyphs with some sort of while lines or highlights on most of the glyphs. ("attachment 6537 [details]#.ps" is the "Simple sample file" from Bug # 691494.) I don't see these artifacts on the master branch.

The resolution does not really matter, but the higher the more clear the white lines are. At low resolutions, the glyphs look just "broken".
