ArcGIS Maps SDK for JavaScript 4.28, one question about LayerList.

Question

Have others encountered the same issue? I'm developing a map using ArcGIS Maps SDK for JavaScript 4.28, and I've noticed that when I add a LayerList, there's a noticeable delay when moving the map. However, if I remove the LayerList, the issue disappears. I later found out that this is because the LayerList listens for layer loading events, causing the delay when moving the map with the mouse. How can I disable this event?

Thanks for reply,here is my sample code: 有圖層清單的MapImageLayer

We are displaying using map services, there are approximately 30 layers, each map service has multiple group layers but not much data inside, probably a few hundred records. However, when using LayerList, there is a delay when moving the map. I later found out that this is because the LayerList listens for layer loading events, causing the delay when moving the map with the mouse. How can I disable this event?

How are you initializing the widget? It could be a problem with the React rendering lifecycle.
