10033: Layer uses symbol level drawing with layer transparency

Your layer is set to use symbol-level drawing with layer transparency. However, the use of transparency in symbol-level drawing can affect the display performance of basemap layers and map services.

Solution

Check the drawing performance for your layer or basemap layer in ArcMap. If you are publishing, check the drawing performance for your service in the Preview window.

• If drawing performance is slow, remove layer transparency from your symbol-level drawing. To do this, follow these steps:
  1. Click the Display tab on the Layer Properties dialog box.
  2. Change the Transparency value assigned to the layer to 0%.

More information

Generally speaking, using layer transparency in symbol-level drawing may result in slower display performance of your map services. So you might want to explore alternative display options for use in maps where performance is critical.

If your application warrants the use of transparency 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 document. Beware that the resulting map will draw more slowly.
