I tested with the following Nvidia drivers, all of them rendered water
correctly:
410.93 (current stable)
415.22.05 (Vulkan beta)
415.27 (current beta)

For the sake of completeness, I tested this bug with the Uplay version of the
game on Archlinux using vanilla Wine (git). The following components were
installed in the prefix, everything else was set up as built-in:
corefonts (needed to launch Uplay)
mfc90.dll (needed to start the game)
d3dx9_40.dll (missing textures in the main menu with built-in).
