Visibility of linear features while drawing over raster

Hi,

 

I have raster attached in background plane in my design model. When I try to draw my linear features (which are defined in geospatial administrator) over a raster i can see only line from the last data point to the mouse pointer. I cannot see all previously chosen vertices of line (Red line on the picture is visible only when I try snap some previously chosen vertice). Those vertices are snappable even they are invisible . I would like to know if anyone has the same problem and how to solve it?

 

I have to say that this is problem only for xfm features in Bentley PowerMap and Bentley Map, not for Microstation smartline/line elements, they are displayed normally during a placement over raster.
