Could you also post the piece of the NetworkUI that sets up the Camera?
I'm a little worried that there might be something in there that's not
threadsafe. We have worked under the assumption that Manta takes care of
thread-safety for the Camera, but I'm not totally sure.
Certainly.
I have also included a picture of the output when manta is running on my laptop with only one processor. Its an amd64. There seems to be a little noise in the image. A little on the sphere and a little on the bottom left of the plane. When there are multiple processors the "noise" moves around the image. This is not the case with only one processor.
