Hey guys, i have reported this in the "Unofficial Bug List" thread already,
but i guess its better to open a new Thread for further discussion.
I hope thats alright.

I have got a weird problem with the water in Whiterun.
If you get too close, look at it from far away or view it from different angles,
it turns completely pitch-black. I play Skyrim on PC with Ultra-High Settings,
my Graphic Card Setup is two Nvidia GTX 580 SLI. The first time i noticed
that problem was after the 1.7 update. The only mods i'm using are the
Unofficial Skyrim Patch and Bethesda's High Res Texture Pack. Here
are some videos i found on youtube that show the glitch in action :

Drivers and stuff are all up to date. If you have any ideas or solutions,
please feel free to tell me. Thanks alot in advance. I hope you guys
can help me.

Sincerely, Rayborn
