In this PR the DISPLAY=:0 environment variable was re-added to the dockerfiles.
It seems that this is now mandatory, otherwise default commands like "winecfg" will fail with an error:
Make sure that your X server is running and that $DISPLAY is set correctly
After adding the DISPLAY var, the default GUI apps like winecfg, explorer, etc work as expected again.
