Error in cache state for GL_VIEWPORT
I am seeing a lot of error messages in ParaView master (373085ad) on OS X. They start with
Generic Warning: In /Users/tjcorona/Development/Software/paraview/source/VTK/Rendering/OpenGL2/vtkOpenGLState.cxx, line 157
Error in cache state for GL_VIEWPORT
and they occur at the program's start.
