It was recently pointed out that the Kube flatpak for Kolab Now does not work with nvidia drivers, leaving you with error messages like this:
libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast Unrecognized OpenGL version Unrecognized OpenGL version
As it turns out this is a problem with the extension system of flatpak that is used to provide the appropriate graphics driver to the application inside the container. It’s not quite clear what the best solution to the problem will be, but we’re working on it.
