Hi I am having a similar problem to this old post:
I noticed this several times, and initially I thought it was the displacement stretching the texture too much, but after checking this tutorial and that forum post I noticed it could be something else.
In addition to the jagged edges, I have this line at the edge of the square that does not make sense, it goes is I play with the offset. So it seems to be the last pixel of the uv space that is showing like the offset was 0.001 or something, but the offset is off and it should not show.
in the screenshot, you see the older tutorial with normal lines, and no edges showing.
I did the checks with tessellation at 10 and displacement like it is said in the other post.
Any help please?
