More information

Map services use a graphics pipeline that can employ a high-performance processing method to draw symbol levels. However, layer masking is incompatible with this high-performance method. If your application warrants the use of layer masking in conjunction with symbol level drawing, you can choose to mark this warning as an exception to avoid receiving the warning next time you analyze the map. The map service will use a slower method to perform symbol level drawing in this case.
