Since 11.1 launched, I’ve noticed a sporadic issue with the spawn of scattered particles from various effects throughout the game. There’s not really a rhyme or reason why it occurs, except that most of the time it occurs as the location of the particles in question first comes in to my game client’s view.
Instead of being spread around normally however these sets are configured, they spawn in a sphere shape and slowly expand outwardly in that shape. I’ve seen it with Mereldar’s braziers, as well as just today in Amirdrassil at the Heart of Amirdrassil platform with Fyrakk. I’ve uploaded a clip of the latter scenario which demonstrates the issue visually.

I also believe I’ve seen it in the House of Chrome inside the Liberation of Undermine raid. However, instead of spawning in a sphere shape, the particles all spawn on the same horizontal plane spanning the entire room, and they slowly move upwards out of the floor and above the platform. This particular variant of the issue can occur after I’ve already been in the room for some time, so the first-time visual on my client isn’t an obvious factor there.
