I am using a FeatureLayer with fill symbols from ArcGIS whose PNG image dimensions are around 75x75 pixels. For polygons of "normal" size (say, a center-pivot sized field anywhere in Kansas), everything works fine, but for very large polygons or multi-part polygons with a large envelope (say, 5 or 6 of these center-pivot sized fields), the Silverlight app fails when zooming in too close (around 1 or 2 meters-per-pixel). I assume it's an issue in the shader used by the TileEffect class but I really have no idea.
Has anyone else run into this? Is there an easy fix or workaround?
