Description

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"

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

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