Hi,
Some additional info regarding this bug:
Performer 3.0.1 linux is affected,
both on nvidia and 3dlabs:
OpenGL renderer string: Quadro4 900XGL/PCI/SSE2
OpenGL version string: 1.3.1 NVIDIA 28.80
OpenGL vendor string: Xi Graphics, Inc.
OpenGL renderer string: Wildcat III 6210/AGP/SSE2
However, Performer 2.5 IRIX is not affected.
Also, the corruption is present in the .pfb file, so it's not
just a perfly bug: If I run the program on IRIX, I can view
the output on linux. If I run the program on linux, the pfb
is corrupt.
Bram
