[Bug]: Render Tests Failure (SDL_RumbleMotor Deps Duplicate)

[jvoids]

🐛 Bug

Hi guys.
For whatever reason the tests started to fail for tests/test_vec_envs.py::test_render
I'm not really sure what could really changed to cause the issue as it definitely run well lately (all the tests)

Previously it was actually normal silent run. But now for the render tests it forces screen switching to a visual displays and then crushes. due Class SDL_RumbleMotor is implemented in both opencv and pygame

Is it maybe just a matter of reconfigure env to disable visual display as it ran previously?

Thanks

To Reproduce

git clone https://github.com/DLR-RM/stable-baselines3.git --depth 1

python -m venv .sb3-venv
. .sb3-venv/bin/activate
pip install -e '.[docs,tests,extra]'
python3 -m pytest -v tests/test_vec_envs.py::test_render
