This mostly only happens in dungeons, I’ve had it happen extremely rarely in certain areas that were not dungeons however.
I’ve been having this issue exactly, however I get it pretty much everywhere, not just dungeons. I seem to get it more pronounced the more there’s happening on screen, but no correlation to other player being in the area, i.e. a bunch of mobs cause it as much as a bunch of players do.
It’s only started about 3 days ago for me, but it seems like it’s getting progressively worse.
As with most other people on this thread, I’ve checked my network connection and it seems to be an issue on the server side.
I hope this will be resolved soon, as the game is near unplayable for me right now
