mujoco.FatalError: GLFWError

[cartacamilla]

I am trying to run the example dm_control.viewer.

I had it briefly running before restarting my system, now I have this error:

/home/milla/.virtualenvs/mujoco-xD_Ta8vw/lib/python3.12/site-packages/glfw/__init__.py:917: GLFWError: (65544) b'EGL: Failed to create window surface: An unrecognized attribute or attribute value was passed in the attribute list'

mujoco.FatalError: gladLoadGL error

From what I've seen, solutions usually recommend prepending MUJOCO_GL=egl, which I've done to no avail.

I have also tried the solutions proposed in #283, also with no success.

I am on Arch using Wayland, on python 3.12, dm_control 1.0.34, mujoco 3.3.6.
