--- Comment #3 from olsentest@comcast.net 2009-03-13 18:07:12 --- I note that bug #8167 (abandoned) identified the same problem. Attachments to that report show output with the same missing semi-circles. The bug report referenced a different application and OS.
I suspect that any application generating graphic output and using the same method (whatever that is) to draw filled semi-circles (maybe full circles?) will experience the same missing components in their printed output.
