           Summary: consider grid-fitting rectilinear paths
           Product: MuPDF

          Platform: PC
        OS/Version: Windows 7
            Status: NEW
          Severity: normal
          Priority: P4

Attachment 6804 from bug 691689 misrenders* most likely due to hairline fills
being anti-aliased:

1 1 0.604 scn % the expected yellow
63.48 738.92 216 -0.06 re f
63.48 738.68 216 -0.06 re f
63.48 738.44 216 -0.06 re f
% etc.

Grid-fitting these paths before filling them might take care of the issue, so
please consider grid-fitting rectilinear paths to achieve the expected
rendering for such a case.

Note that Adobe Reader "mis-renders" the document in a similar way if the
"Enhance thin lines" option is disabled.

* Misrenders means that the title backgrounds on pages 2 and 3 appear
semi-transparent when the apparently expected result is a solid color
