God damn pirates stole my PBC beams on Linux! You know, those orange beam trails that show up every time a lasertower or a PBC weapon gets fired. They are nowhere to be found using GOG's latest offline X3 - Terran War Pack installer for Linux.

And, to no surprise, the problem seems to be specific to the GOG Linux build (potentially only the offline build as well... Galaxy might be fine, urgh).

More info and a workaround on this thread over on the Egosoft forums: https://forum.egosoft.com/viewtopic.php?f=93&t=456753

As to when (if ever) we will get a proper fix... probably never IMHO.
