Terris Bezner commented on VWR-8211:

I have now FOUND A SOLUTION for this bug which gets rid of the black water while still allowing you to see Nearby Local Lights, Fog and Atmospheric Shaders. It appears the viewer does indeed include a fix for this bug, but it is not activated by default.

Steps to fix:

1) Enable the Advanced menu by pressing Ctrl-Alt-Shift-D
2) Open the Debug Settings dialog by pressing Ctrl-Alt-Shift-S
3) Select (or type in) RenderShaderLightingMaxLevel. The caption should read: "Max lighting level to use in the shader (class 3 is default, 2 is less lights, 1 is sun/moon only. Works around shader compiler bugs on certain platforms.)"
4) The default value is 3. Change it to 2, press Enter, and close the dialog.
5) To activate the fix, open Preferences > Graphics > Custom. Under Lighting Detail, change to "Sun and Moon Only" and then change BACK to "Nearby local lights". When you do this, the black water should vanish.

Can anyone else with this problem confirm that these steps work for them as well?
