I have a graphics layer, that is loaded first and I want to keep it on top while other layers are loading. Therefore I insert other layers to the position before the graphics layer. The problem is that the graphics layer is flashing everytime new layer is inserted. The best way how to reproduce the issue is when I remove and add the same layer over again, see sample code in attachments. It looks like the graphics layer is refreshed every time I insert a layer, how can I disable the refresh?
