I can also confirm that DX9 does not have the artifact, only OpenGL. With DX9 however the trees are strangely hovering about. This strange wobbling disappears when the vertex shader is disabled.
Clearly, this seems to be a problem with the vertex shaders, or the way the GTX 1080 interprets them.
Unfortunately without the shaders a lot of visual detail is lost (for example the grass disappears entirely, and some textures become very dark)
