My current (although damaged) salvage ship has a cockpit inline with the ends of the cannons, and I can see the beams, I also have plexiglass over the cannons and cockpit. I have had problems with past ships, and occasionally with my current one. Haven\'t used it in newest update though.
maybe related, but I also have problems seeing missile traces when they are fired out of my view range, as me and a friend found out when he shot a BB locked onto me accidentally, too my side. No damage due to shields, but worrying as I couldn\'t see the missile even though I had turned to where it was coming from to me.
