What's the problem? Describe what went wrong.

When running Xenoblade Chronicles in the D3D12 backend with the texture cache at the middle setting (between fast and slow) the grass textures in the starting town are hosed. Sliding it over to Slow fixes it instantly. I can't reproduce this in D3D9 but it might just be intermittent. I've seen it twice.
Doesn't seem to happen if you're using custom textures.

What steps will reproduce the problem?

D3D12 backend, texture cache accuracy at the middle setting (between fast and slow). Load a save on the entry bridge in the starting town, looking outward towards where you start the game.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

Tested in 4.0-8947. Haven't used Dolphin in like a year so I don't have any good comparison versions here (and obviously, the D3D12 backend wasn't in those versions).

What are your PC specifications? (CPU, GPU, Operating System, more)

Haswell-E CPU, GeForce 980ti (latest drivers as of 2016-02-16), Windows 10 x64.

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
