Nanite foliage with WPO enable is frustum culled by the original position without WPO. When wind is blowing hard, it is very obvious on the screen edge where some leaves are culled and left behind an empty margin. Is there any way to solve this problem, like maybe increasing bounding box on each nanite cluster? I failed to find such settings. Or will this problem be fixed in future releases?
It seems this problem is fixed in 5.2. There is a Max World Position Offset Distance setting in the Material Property Overrides section. It will clamp the wpo value as well as increase the nanite cluster bounding box.
