The environment geo is getting in the way and the particle's wireframe outline is the same color as the environment. A current workaround it going to the Preview Scene Settings and turning off the environment or changing the backgrounds color.

This is only an issue with Niagara, Meshes and material's wireframes aren't the same color as the background color.

Steps to Reproduce
  1. Open any project
  2. Within the content browser create a Niagara System
    1. New System from Selected Emitter(s)
    2. Select a Fountain Emitter, +, then Finish
  3. From the preview window select the Lit tab and change it to Wireframe

The wireframe is very difficult to visualize when utilizing the default settings
Expected Result:
The wireframe is easy to see
