There could be some reasons for this to happen, the most possibly could be that It might just be a visual artifact, not actual height data, that checkerboard/dither pattern across the whole terrain looks a lot like a scene view artifact rather than real heightmap noise. Check:
Scene view camera for disable Temporal Anti-Aliasing (or switch to FXAA/None) and see if the pattern disappears.
If you're on URP/HDRP, check Project Settings then Quality then Dithering and any post-processing volume with Depth of Field or Bloom active in the Scene view, these can produce exactly this kind of grid noise on flat-shaded terrain.
Try switching Scene view shading to Wireframe or Shaded Wireframe briefly to confirm whether the mesh itself is jagged or just the shading looks noisy.
