How can I turn off the function of stretching tiles several times when zooming in and out of cesium

Hello everyone,
I have a question.
When I load the ArcGIS dynamic service on cesium, cesium will stretch and display low-level tiles when zooming out and zooming in. When I encounter that ArcGIS can’t immediately return tile images, half of the screen on the map will be stretched and blurred tiles, and the experience is very bad. How can I turn off the function of stretching tiles several times when zooming in and out of cesium?
Would you please give some suggestions? Thank you!
