Oh it is definitely an issue. Starting to wonder if they are going to do sunsetting 3.0, because the game is struggling to keep up, and with two major expansions and their respective seasons to go, the performance issues are getting bad. Not that I ever want sunsetting 3.0. Just seeing what might be the preverbal writing on the wall here, as it’s getting bad

Not sure if you have already, but report it as a bug in the help forums, and try to give as much detail as possible. Images, videos, what you were doing or what activity you were coming from. A problem can't really be known or tackled if you don't report it to them in the area they look and give them details to try and reproduce it.
