Heavy lags when connected with debugger to Android on VS2019 16.9.2 and newer #297

When using VS2019 16.9.2 on Windows, the app becomes unusable as long as FlowListView is in it. Every page that uses this control lags as hell when the debugger is connected. As soon as there is no debug connection, I use a older VS2019 Version or removing FLV, I have no lags at all.

There was a similar known issue with SkiaSharp which is solved in the latest version there. Maybe it's kinda the same problem. See: https://github.com/mono/SkiaSharp/issues/998

Seems like this comes from a memory leak in ListViewCachingStrategy.RecycleElement.

The issue still exists. It keeps creating thousands of views which can be observed from the live tree:

However there are only 12 items on screen.
