Landscape raytracing geometry always updates every frame

LOD 0 Landscape meshes are always updated in FLandscapeComponentSceneProxy::GetDynamicRayTracingInstances because* r.RayTracing.Geometry.Landscape.LODsUpdateEveryFrame* (GLandscapeRayTracingGeometryLODsThatUpdateEveryFrame) defaults to 0 and bNeedsRayTracingGeometryUpdate evaluates to true.

Setting r.RayTracing.Geometry.Landscape.LODsUpdateEveryFrame to -1 prevents this behavior.

Steps to Reproduce

1. create a level with a landscape actor
2. enable ray tracing in the project
3. set a breakpoint in FLandscapeComponentSceneProxy::GetDynamicRayTracingInstances *on *Collector.AddRayTracingGeometryUpdate

Expected

After all Landscape raytracing geometry is uploaded the breakpoint isn't hit until the camera moves.

Actual

The Landscape meshes with LOD 0 will continually hit the breakpoint and have their raytracing meshes updated.
