`has_offscreen_render=True` does not work (GLEW initalization error: Missing GL version)

[RayYoh]

Describe the bug To Reproduce When I use the Quickstart codes of robosuite, it work perfectly when I use:

env = suite.make(
    env_name="Lift", # try with other tasks like "Stack" and "Door"
    robots="Panda",  # try with other robots like "Sawyer" and "Jaco"
    has_renderer=True,
    has_offscreen_renderer=False,
    use_camera_obs=False,
)

But when I use:

env = suite.make(
    env_name="Lift", # try with other tasks like "Stack" and "Door"
    robots="Panda",  # try with other robots like "Sawyer" and "Jaco"
    has_renderer=False,
    has_offscreen_renderer=True,
    use_camera_obs=True,
)

it dose not work, and there is an error GLEW initalization error: Missing GL version.

Give up immediately. Instead, use 'OpenGL.GL.glReadPixels ()'.

@SATE001 can you elaborate more on your response? (like some small example with some environment)? Thanks!
