Either theres a rave party going on in your ship by your BOFF's or the effects from the champions online update are applying to your ship for whatever reason.
Do you have CO installed at all? I recognize the effect. It could be maybe a config setting or leftover code from the CO update is now in STO?!? Not entirely sure but I have seen that effect before in CO since their last update.
Its not game ruining, but it sure is sad to see, I've seen similar things happen all over the game since the last patch prior to season 4's launch.. I've reported them but since everyone was more busy looking at the new 'toys' the looks of the game got ignored
