Yes, as Aeryl said, this sometimes occurs in the Blue Mountain and Besieged Farmlands, with an infrequent appearance in Hell Eternal. It can also occur during Occult Defence Scenarios, but typically only at the highest waves.

When it does happen, it is generally after your client has gone from one side of the enormous playfield with a huge amount of mobs on it to the other in an instant, either through death or an Anima Leap.

Restarting your client is the fastest solution. Repeating the action that caused the bug or allowing it to naturally do so on its own end can indeed cause it to go away at its own pace.

This bug is often informally known as the ‘flicker bug’ due to the world flickering in and out when your camera moves. It is unrelated to the Elemental spell “Flicker”. I personally prefer to call it the ‘world flicker bug’ to prevent confusion between Flicker itself.
