ListView BeginRefresh EndRefresh causes pointer to show on XF Android

I recently added ListView BeginRefresh and EndRefresh to resolve another bug. However now, an artifact is displayed on each item added to the ListView. Its like a finger touch or scroll white dot. It displays over and over with each item added. I have only tested this on emulator so far. What is this all about?

Code
listViewPlayers.BeginRefresh();
observableCollection.Add(player);
listViewPlayers.EndRefresh();

• White dot is quickly shown in emulator
