Hi there, I think i have fixed the popular FNaF displacement map that a lot of GDevelop devs use for FNaF games, the old one (in the image bellow this text) is good but at the left and right edges of the screen it gets weird but I think I fixed it by editing the image.

Mine ↑
This one is even better than mine: Even better 3D displacement map!
