Graphics are hidden on map after migrating from JavaScript API from 2.5 to 3.2

Hi,

After migration from JavaScript API from 2.5 to 3.2, the graphicsLayer suddenly was hidden from map. It happens only when doing panning operation.
I have a special handling for the events "onPanStart" and "onPanEnd".
When "onPanStart" happens - I hide all the graphics layers
When "onPanEnd" happens - I show all the graphics layer.

Everything works fine in version 2.5, but after upgrading to version 3.2 - the graphics suddenly hidden after pan operation.
When I doing zoom operation, the graphics layers become visible.
I cancelled the handling for "onPanStart" and "onPanEnd", and the problem didn't happen.

I really appreciate any assistance, because I can't upgarde the API version because of this critical issue.

Why not use displayGraphicsOnPan: false when you create your map so that you don't need custom event handlers to hide/show your graphics?

I am using custom handling , because we need to hide specific graphics layers and not all layers.

Understood. Can you post code that reproduces the issue? Preferably a simplified version of what you're using.
