Terrain flickering/artifacts when camera moving on Y-axis

hey everyone,
I have an issue with my scene where my camera follows my character..
but only when the camera zooms in or moves on x-axis terrain starts creating odd artifacts.

Three terrains on scene, only two are in cameras vision the one located on the far back of scene (it isn't overlapping front terrain)
and one in the front of scene
Back terrain LxW - 500x100
Front terrain LxW - 100x55
