Has anyone experienced this? I'm using developer edition 2.4 and users have been complaining about 3 to 10 second pauses when zooming.
I tested the map itself by viewing the it in portal, it displays correctly with no pauses at all. Then on a whim I stopped the layer list widget in the app from automatically loading on startup of the web app, this gave a near instantaneous zoom response. Then I opened the layer list widget manually and the pauses in zooming had returned. Additionally, after closing the Layer List the zooming pauses remain as the widget isn't automatically unloaded when closed.
This map does have a moderate amount of layers, however there are no pauses zooming when viewing the map in ArcGIS Portal, or when the layer list widget is disabled in the web app. This is making me suspect a bug where the map is waiting to draw while the layer list is doing something else. Perhaps it's checking weather each layer is visible at that scale??
Does anyone have any ideas as to what I'm doing wrong, suggestions or a work-around that I could try?
