Slow performance issues in ArcGIS Pro when there is a large number of layout elements

Description

It is possible to create and add layouts to projects in ArcGIS Pro. In some instances, using a layout with a large number of layout elements results in slow waiting time after each pan or zoom of the layout, which interrupts workflow.

Cause

There are several reasons for this issue. Refer to Problem: Rendering and drawing performance issues in ArcGIS Pro 2.0 and above for more information. Additionally, the following are possible causes related to a large number of layout elements in ArcGIS Pro:

• The text uses a halo with a complex fill, an outline, or a transparency setting.
• The symbols are too complex.
• The map series is enabled.
• The ArcGIS Pro project is saved on a network drive.
• ArcGIS Pro is outdated.
