When switching from Scene Depth Collision to Distance Field Collision for a GPU particle system the preview window flickers, but returns back to normal when switching back to Scene Depth.

Found in 4.20 CL# 4369336, 4.21 CL# 4613538, 4.22 CL# 4715968

Steps to Reproduce
  1. Open the Editor
  2. Enable "Generate Mesh Distance Fields" and restart the Editor
  3. Create a new particle system with GPU type data
  4. Add a collision module and set its collision method to "Distance Field"

The preview window of the particles will flash and glitch when switched to Distance Field Collision.

The preview window should display the particles functioning as they would when placed in the editor.
