Description Chris Liddell (chrisl) 2011-07-21 09:17:07 UTC

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.

I have not been able to duplicate this.  I've run hundreds of tests with different options on various machines and have never seen this issue.  I've notified the customer.
