MATLAB is selecting SOFTWARE rendering and then quits issue

[sudbrack]

I have tried your exact copy of the Dockerfile in the repo to build locally and then run in VNC mode I get this error,

I also tried a modified version of your Dockerfile to just get the toolboxes I need from MPM as well and same error.

I also did a GitHub Actions run to build this Dockerfile to eliminate if it is a building issue on my laptop but this also has the same error when pulling down and running.

However, if I pull your image down and run in VNC, it works great. I have also tried the official image like mathworks/matlab:r2024a and mathworks/matlab:r2021b and they also work fine in VNC mode.

This issue has been resolved for me after using the new matlab-dockerhub branch Dockerfile to build and run locally in VNC mode.
