Is anyone having issues with GeForce GTX 1060 3D showing stripes of black terrain?

[Shandalar Al Tambol.9683]

I'm running GW2 64-bit client with new GeForce GTX 1060 graphics card with 3 monitors.

I'm also running Windows 10 Pro in x64 mode with 16gb of memory, and Intel i7-4771 CPU @ 3.50GHz

When running in 3D mode, most of the terrain is black, with occasional stripes of "normal" terrain.

Naturally, when I turn of 3D mode on the GTX 1060, everything is displayed fine.

And it makes no difference whether I run 1 or 3 monitors!!!
