I am running os 10.4.9 and I have tried on an old g4 and a new g5 with an ATI Radeon 9800 XT to make some gem objects but when I get small or I make a thick outline parts of the object dont render and seem garbled. Im wondering if there are any extensions that I need to install in order to get it to work properly. It is the latest Gem and I am running PD .40.2.
