This issue is not reproducible in ArcGIS Web AppBuilder. If the issue persists, contact Esri Support Services, as additional information is required for further investigation.
解决办法
Create the web map with the vector tile base map and data needed.
Open up the web map in the new map viewer instead of Map Viewer Classic.
When wanting to create a web app, create an Instant app or use ArcGIS Experience Builder.
When using either of these web applications, the base map along with the data is rendered properly when zooming in and out of the web map.
