The repair gun effect is so weird. In our mod, TAC2, we used to have it so that if a passenger of a vehicle started repairing that vehicle, he could then look away and the repair process would still continue no matter what direction he turned. Well this caused the beam to do all sorts of weird bends and angles to try and reach the vehicle.
We eventually replaced the beam with a different effect because of the way Tribes2 updates (or doesn't update) the end-point of the repair beam. It turns out the only time the repair beam end point is updated (ie, moved) is if the player who's repairing has the target he's repairing in his line of site. Otherwise, the end-point won't update and stays in a fixed spot and the beam just gets longer and longer until the repairer has LoS on his target again, at which point the end-point gets updated for everyone in the game.
I suspect there's some sort of funky thing similar going on in that screenshot
