displacement map problem

Hi, I put a material from quixel suite and I put a dusplacement map on it.
The problem is on the picture, there's some kind of grid visible .
My shader is black and white with no defects.

The problem is for sure due to displacement, but why ?

Thanks for your help

Hi,
unfortunately, your screenshot is in low quality and I'm not able to read your settings, anyway, try reducing the rey epsilon value in the kernel settings because displacement is affecting the minimum distance between surfaces ;)

ok, I'll try.

it seems to be related to uv mapping.

when I put the material on a new deformated plane without uv mapping (made for quixel texturig test ), it works normaly.
