displaced landscape tears / seams

i have this landscape material and when i use tessellation / displacement i can see tears / seams on the landscape as shown in the following video:

i tried having constant as tessellation multiplier instead of a parameter, tried various displacement textures, also tried that crack free displacement option that doesnt seem to work (does not tessellate the landscape properly or something is wrong with the coordinates, but also produces huge tears / seams)

can anyone help?

Definitely its a material-> tesellation problem. Can you provide any source material to recreate the artifact? (Such as textures and most important the material settings)

ok i will try to replicate the problem with simple materials and textures and upload them

ok here you go,

i created a new scene as simple as it gets, and the problem is still there. its not as exaggerated but its still there.
when you open the scene, dont move the view, the tear is just in front of you.
(selecting the landscape makes tears more visible because of the yellow outline)
