When using Boardviewer with Wine's D2D1 implementation the performance of
scrolling or zooming is slow. Using native D2D1 performance is great.

1. You need to download Boardviewer http://boardviewer.net/
2. Open any boardview diagram for example this

3. Scroll or zoom-in zoom-out and see how slow it is
