It's not working, even a simple xeyes docker fails to open display:
vdheuvel@arthur:/data/home/vdheuvel$ docker run --rm -it --net=host -e DISPLAY -v $HOME/.Xauthority:/root/.Xauthority fr3nd/xeyes No protocol specified Error: Can't open display: :50.0
Makes sense, since it sounds like the UNIX socket is not passed through to the container.
I'm not sure why your TCP workaround worked in the past, though. The DISPLAY syntax should be local-socket-specific (either UNIX socket or abstract UNIX socket), without a fallback to TCP.
To use TCP connections, you'd have to specify DISPLAY=localhost:50.
The more curious thing here is that normally Xlib tries to connect via an abstract UNIX socket, which theoretically should be also available in a container - unless docker prohibits that, which would be plausible for security reasons.
