Clear Opengl framebuffers on open
Please clear the Opengl frame buffers upon ParaView open. Actively overwrite the front and back frame buffers. Currently, on Linux, when you run Paraview , visualize something and close ParaView, (or any other 3d program), and then reopen ParaView, the old frame buffer pictures show. This is potentially a big issue if someone is showing a coworker something, and said co-worker sees something he/she should not see.
Talk to me if you want a more specific example.
