Hello there:
I’m using SNAP in a multiuser server that we connect using X2GO client. It is a setup very similar to RUS machines where the host does not have a dedicated GPU for each VM. The server is running CentOS 8 OS with all the updates installed and mesa packages installed.
While other versions of SNAP had problems with WorldWiew module because the use of openGL acceleration always worked when this module is disabled. However I tried to disable it as suggested here (by enabling flat only and removing the jar file) and product library still have rendering problems. The system shows the following error:
javax.media.opengl.GLException: AWT-EventQueue-0: X11GLXContext.createContextImpl ctx !ARB, profile > GL2 requested (OpenGL >= 3.0.1).

Any ideas on how to fix it? It is quite strange because it requests OpenGL >= 3.0.1 but detects 3.1.
Thanks!
