           Summary: pdf file shows banding problem
           Product: Ghostscript
           Version: master
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Graphics Library
        AssignedTo: ray.johnston at artifex.com
        ReportedBy: chris.liddell at artifex.com
         QAContact: gs-bugs at ghostscript.com
          Customer: 850

Customer says:
'Consultation_boards.pdf' is sometimes not rendered correctly:
a. The second quarter strip from top was completely gray
b. That 2nd strip was rendered into the last quarter (and hence the last
strip was also incorrect)
Unfortunately this happened very, very seldom (I saw this only 2 times on
my PC, using our software with dbg-build gsdll32.dll) hence I could give
you only rough information:
-dNumRenderingThreads=2 -dBufferSpace=200000000 -r600x600 -dNOCIE -dNOPSICC

I tried a few times to reproduce the problem, and could not.

I've assigned to Ray as it is likely a clist and/or a threading problem.
