Holes and cracks in Landscape + Displacement

I yet installed the UE 4.12.3 version.
¿¿Is there a way to avoid cracks and holes in landscape actor when using it with world displacement??
With low height values works fine , for example 3, 8 ,10…but after a high number (60-100) the seams begin to broke.
I think taht for that low values dont compensate the use of displacement maps.

For Static meshes works fine.

Make sure crack free and adaptive are both unchecked in your material. They both cause cracks.
