Huge performance/graphical issues under load (Blight)

PS5: I've seen this several times this league, don't really recall it being an issue in previous leagues (not even on PS4) so might be a new bug.

When I play Blight in maps (at the moment can't recall if it ever manifested in Blighted maps) sometimes when there's a lot of enemies the game seems to give up displaying graphics on parts of the screen. The individual tiles randomly flicker in and out as if trying to keep up. At worst, the whole screen seems to be not displaying for a period of time.

I've captured a minute-long video of this and I would attach it if it was possible but it's not. It roughly shows when the issue starts happening, how it looks and when it stops. Can provide on request.

Might be worth noting that I'm playing a projectile-intensive build, not sure if relevant.

I think so.
I've had this on my PS4 for a long time now. Especially on the map with the Harbingers. The entire screen goes blank. Only the UI and loot remain. Individual tiles don't load very often either.
I don't pay attention anymore. It's sad.
