I understand from your issue that you are getting the warning "MATLAB is selecting SOFTWARE OPENGL rendering" when MATLAB is opened on a Linux RHEL8 machine for post processing. The possible reasons for the error and their fixes are mentioned below.
- Check if the drivers are up-to-date on your machine. Outdated or incompatible graphics drivers can cause issues with software rendering.
- Ensure that your system supports the required version of OpenGL. This can be checked by running the following command in the terminal:
glxinfo | grep "OpenGL"%ghjj
- You can try opening MATLAB from the terminal with the following command and check if hardware rendering is selected.
matlab -nosoftwareopengl
