MujocoEnv render(mode = 'rgb_array') throws GLEW initialisation error, but render(mode='human') works.

[eugval]

With Reacher-v2, and exporting LD_PRELOAD as described here , the issue ERROR: GLEW initalization error: Missing GL version gets fixed for rendering in "human" mode but not in "rgb_array" mode.

A workaround I am using is to call render("human") once, then call render("rgb_array") normally.

Is there something I am missing, or a more elegant way to fix this?

This looks like a mujoco-py issue, could you file this on the mujoco-py repo? Thanks!
