The flicker is visible in Epic scalability as well, it is just smaller on screen because the fog voxels are smaller (r.VolumetricFog.GridPixelSize).

Steps to Reproduce

1. Download the licensee repo and open.
2. Open the map /Content/BugFogFlicker/BugFogFlicker.umap
3. Set scalability to High
4. Align the bottom of the viewport with the bottom of the screen.
5. Observe the increase in flickering.
6. Repeat steps 4, 5 with the right edge of the viewport and right edge of the fog.
