Research direction

Reproduce the issue in the Sponza scene using 540 GI Probes, a shadowed directional light, disabled skybox lighting, and GI calculation with 2 bounces. Inspect the lens flare and GI Probe rendering paths involved when moving the view near the Lion Sconce. Done means lens flares behave normally after GI calculation with more than one bounce.
