Using containers might reduce performance. If it does matter to you, use local build. Reduced performance might be useful to observe how interpolation of players position works (shadowing method without queue).
Client docker image uses host X11 server to display GUI which requires authentication in most cases.
The fastest and simplest method to bypass authentication is to run xhost +local:root before use and xhost -local:root afterwards (it is important to not forget to execute the latter - reference).
docker-compose build and docker-compose up.
