JSAPI 4.2 - mapView SIGNIFICANTLY slower performance

Hello Community!


I usually do not reach out to you, but I am quite concerned and had a bit of a rough day.


You see I upgraded our app from 4.1 to 4.2 and saw a dramatically slower performance with the mapView and our tile layers. We did see improved performance for sceneView and less click even slippage, which continues to be a major problem for us.


When I switch back to 4.1 my experience is fluid, handles wobbling and fast scrolling just fine. However 4.2 panning, zooming, and click events are lethargic, sluggish, and downright frustrating.


I would like to accomplish the following from this post:


  1. Confirm with the community that they have experienced a similar issue.
  2. Get clarity if mapView is going away under jsapi 4 and expect it to become more diminished.
  3. How long can I keep using 4.1 in production?
  4. I would like to get support to look at our issue, specifically someone from the jsapi team for a contracted few hours. Not sure how to approach that.
