--- Comment #155 from Wojtek Arabczyk arabek@gmail.com --- Verified the same for the Intel GPU:
[ macbook: ~ ]$ glxinfo | grep OpenGL OpenGL vendor string: Intel Inc. OpenGL renderer string: Intel HD Graphics 4000 OpenGL Engine OpenGL version string: 2.1 INTEL-10.2.46 OpenGL shading language version string: 1.20 OpenGL extensions: [ macbook: ~ ]$ glxinfo | grep vertex_blend GL_ARB_vertex_blend, GL_ARB_vertex_buffer_object, GL_ARB_vertex_program,
I'll retest on Linux opensource & closed drivers later.
