We are using graphics layers for many purposes.
When we checked v4.13, some layers appeared partially.
This happened only in big datasets.
My temp solution was to use featureLayer, and yet - it happened again in another part of our system.
I took the basic graphics example and managed to catch the point when the problem starts => more than 2205 graphic items.
I've created a simple codepen - https://codepen.io/nettaben/pen/QWwqbjy
Change `maxItemsV413` to 2204 to 'view' the markers ==> stops working when the number is greater.
If the api version is set to 4.12 - it is possible see more than 2205 points, while in v4.13 - it is not possible.
(change in the example).
UPDATE: not working with 4.14 as well.
