*Edit* - I have seen a few lets plays on YouTube. Older versions of BP didn’t do this, but a lets play from 2018 did. You can see it here: https://youtu.be/Arg4vZffYwU?t=7721 (https://youtu.be/Arg4vZffYwU?t=7721)You can clearly see the player getting hit by a missile at the start of the effect; Arjuna wing, at the very least, is loaded with "EMP Adv.#Shivan" secondaries, so... avoid the EMP missiles and your HUD won't go screwy, pilot!
Is it due to getting hit? Is the psychic link to the ship being disrupted? Or is it some of the fighters or bombers that are doing it? I notice some of the Maras are the assassin intron which gives them temporary cloaking ability. Is there an intron that scrambles sensors etc?
Compared to any GTVA gun they're totally ridiculous, especially the flak and beam. However their rapidfire heatseeker isn't as broken as the Tempest so you're losing some DPS there and you're fighting Shivan introns with massively buffed health so it seems as if you're doing no damage even though you're still doing loads of it.
