Skylighting on distant objects causes severe flickering with Lumen

Lighting on distant meshes flickers when using Lumen and Skylights.

Turning Lumen off and lighting from the skylight is stable. Turning off Lumen screen traces also lowers the amount of flickering, though it doesn't completely eliminate it.

Steps to Reproduce

• Create a scene that is lit with at least a skylight (or open the *L_IsolatedEnv *level in the attached repro scene)
• Place a large object far off in the background

Expected

Lighting on distant object remains constant and stable.

Actual

Lighting from the skylight with Lumen enabled will cause severe flickering on that object
