Description

This is a regression from 4.24.3 (CL-11590370). SSR begins to flickers when AA is disabled when moving around the scene.

This was reported and tested in 4.25 (CL-13144385) and reproduced in Main 4.26 (CL-13408123)

Steps to Reproduce
  1. Open the UE4 Editor and create a Blank project
  2. Create a reflective material and apply it to the Floor in the Default map
  3. Add some Cylinders to the floor to help show the reflection
  4. Disabled Anti Aliasing with r.defaultfeature.antialiasing 0 and build Lighting
  5. Move the viewport camera closer to the cylinders

Results: Screen space reflections flicker

Expected: Screen space reflections should work as per previous versions
