Hello, are the any news on this issue? Although this bug is still standing on "approved", it seems like if it is fixed in the latest Xamarin UI release v2019.3.1119.1 (that's the latest version in Visual Studio 2017 NuGet Manager, your release history says lastest version is v2019.3.1119.410). So, scrolling seems to work without flickering now. But a new bug occured..
When you expand and collapse a parent treeitem several times, it will happend, that child treeitems loose their height if they are higher than 44px. So a child treeitem can fall back from a height of 150px to 44px. On the next expand and collapse it will have a height of 150px again. Another thing is, other parent treeitems that have a fixed height of 44px, could have a height of 150px now. It seem like if treeview virtualization is still broken. Can you approve this?
