Runescape in container

Hey, sorry if this is in the wrong category.

I am trying to get runescape running inside docker. I am able to get the GUI working, but it gets stuck at “Loading resources”. Is there somewhere I could get some logs? I use ubuntu:18.04 image and checked /var/log - all logs are empty except apt-get logs.

Or if anyone could suggest a direct solution I would be more than happy.

Try docker logs <container>?

I have already tried that and it is empty. Well its not empty, but it shows just one line, even with --details argument, then it shows two lines. One of the command that executed and another of GTK failed to load module - but its normal. The error even comes in host, when no container is used, but the application still runs.
