Since it doesn't happen with no addons, but does happen with just nUI, it appears to me to be a nUI bug. The best I can figure is with the new water texures, the reflections and ripple effects are being overlaid and aren't being scaled when nUI scales the rest of the viewport. Or I could be completely wrong.

EDIT- I tested this theory by disabling all addons and installing Sunn Viewport. Running only this viewport scaling addon also causes the weird reflection effects.

EDIT2 - a quick Blizzard Forums search for "viewport water" shows several posts of people pointing out that any addon that resizes the viewport gets the weird water textures. Everything *except* the reflections scales properly.
