vrayWater texture and GPU rendering - gridlines

[chronopsis]

Attempting to render a simple plane using the vrayWater texture. CPU rendering is fine, but GPU rendering (faster) produces displaced line artifacts, which seem to match the plane's original geometry, but displaced. Kind of cool, but don't want it!
Maya 2019.2, lastest vray 4.3. Mac Pro 5,1, 10.13.6, Titan X GPU.
