A pair of places where flickering of OBJECTS is especially objectionable is ... Starfleet Academy and the Klingon Academy. I am referring, of course, to the Isolated Particles that are spawned during the Academy Event (on Holodeck).
In the case of Starfleet Academy, it seems like ALMOST ALL of the Isolated Particles in the outdoor locations (along the walks and paths) have this "triple superposition" problem when they spawn. I'm referring of course to once these objects reach the Expanding Particle/Dissipating Particle phase, where for some reason these objects FLICKER MADLY at a rate that would no doubt be seizure inducing for people who have medical issues with strobing lights and crazy fast flicker rates. Just being able to READ the words Expanding/Dissipating is difficult, because the object display WON'T HOLD STILL. When doing the Starfleet Academy Event, I'm often reduced to trying to discern (in an over 60 Hz flicker rate between 3 visual locations) if words start with either "Ex" or "Di" because that's all I can read (and differentiate).
Klingon Academy is not NEARLY as bad about this as the Starfleet Academy. Unlike the Starfleet Academy (where a supermajority of the Isolated Particles exhibit this problem), at the Klingon Academy this problem appears to only occur in a couple of locations where the Isolated Particles spawn in close proximity to walls, and thus are relatively easily avoided, since they represent only around 5% of the spawn points.
Ironically, however, there's a couple of Particle Spawn locations at the Klingon Academy (not the same as the madly flickering Isolated Particles) which are placed so ... badly ... as to be behind Invisible Walls so as to make them completely inaccessible. The worst of these is a Particle along the path into the cave with the Exchange/Bank/Mail computers where the Particle itself can be scanned, but if it spawns a Starfleet Officer to attack you, the hostile will be placed on the OTHER SIDE of the Invisible Wall, meaning they can attack you (and they do, with impunity) while you can neither Target nor attack them ... unless you "Run Away" and kite them out of their invulnerable Invisible Wall spot where they spawned. Thankfully, it's just the ONE location at Klingon Academy that does this, making this problem "easily avoided" as well, although it's still glaringly broken whenever it occurs.
Anyway, the "Crazy Flicker" on Isolated Particles (either Expanding or Dissipating) during Academy Events needs to be tossed onto the bonfire of Flicker Issues to get resolved at some point (although in this case it's an interactable Object rather than an environment Background).
