[5.3.2] Distance Fields issue in Steam build

Hello !
After updating our game from 5.2 to 5.3.2, we noticed the lighting was broken in the Steam build. (it’s fine in editor). The project has not HWRT.
It seems to be due to Mesh distance fields not being generated/loaded properly ?

ShowFlag.VisualizeMeshDistanceFields 1
in editor

ShowFlag.VisualizeMeshDistanceFields 1
in steam build

In steam build after zooming out the camera a lot and coming back some MDF appears properly and lighting improve.

I also notice that now in 5.3.2 both in editor and steam build GlobalDistanceField visualizer seems to be broken ?
