OpenGL2: quadro 4000M-specific error
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
On a Quadro 4000M, I obtain the attached error.
glGetString(GL_VERSION) returns 3.2.0?
After adding
#extension GL_EXT_gpu_shader4 : require
in the header of the FSSource shader version 150 in vtkOpenGLShaderCache.cxx, everything works fine.
