ERROR:buffer_manager.cc(488)] [.DisplayCompositor]GL ERROR :GL_INVALID_OPERATION : glBufferData: <- error from previous GL command

Describe the bug After successfully installing SLM-Lab and proceeding to the “Quick Start” portion which involves running DQN on the CartPole environment, everything works well i.e. (final_return_ma increases).

Command entered: python run_lab.py slm_lab/spec/demo.json dqn_cartpole dev

After several log summary and metric instances an OpenGL error code occurs :

[101017:1015/191313.594764:ERROR:buffer_manager.cc(488)] [.DisplayCompositor]GL ERROR :GL_INVALID_OPERATION : glBufferData: <- error from previous GL command

and then the process seems to end without showing any graphs.

To Reproduce

1. OS and environment: Ubuntu 20.04 LTS

2. SLM Lab git SHA (run git rev-parse HEAD to get it):dda02d00031553aeda4c49c5baa7d0706c53996b

3. spec file used: slm_lab/spec/demo.json

Sounds good. An issue was opened. Thanks once again.

Thank you once again. However, after updating plotly-orca, the same errors occur.
