Tesselation Material Flickering with vertex painting

Hello, I am creating a material with tessellation and vertex painting, however when i push the distance values for the height map beyond 2 it starts to flicker. This is what I get.

Thank you for the help.

Pretty sure it is expected and happens because the mesh starts to extend past its original boundaries and various visibility checks start to fail. You can increase objects bounds scale in static mesh editor to avoid that.
