Steps to Reproduce

• Login on Project Alex Ivy, or any other 64bit viewer on a system with Nvidia graphics running the new Nvidia 378.49 graphics driver.

• Disable ALM
  Preferences -> Graphics -> Advanced Lighting Model

  Observed Behaviour

• On Nvidia systems, after updating to Nvidia graphics driver 378.49, the world view is tinted blue when ALM is disabled.

• See Fig 1 (ALM disabled) & Fig 2 (ALM enabled) attached.

• When ALM is enabled, disabling Glow mostly fixes the problem, apart from the Linden water still has an off brown tint.
  Advanced -> Show Debug Settings -> RenderGlow

• When ALM is disabled & the bug reproduces, disabling Bump mapping & shiny then re-enabling Bump mapping & shiny fixes the problem until ALM is toggled again.
  When ALM is disabled & Bump mapping & shiny has been disabled then enabled (so the bug is "fixed"), disabling Bump mapping & shiny will then reproduce the bug again.
  Preferences -> Graphics -> Advanced -> Bump mapping & shiny.

• Some Nvidia system seem to be unaffected.
  So far 2 users with Titan graphics cards have been unable to reproduce this.
  I'll add a table below of known affected cards.

• So far all cases of this bug reported have been on Windows 10 and quite a number of users with cards that should be affected report no bug on their Windows 7 systems.
  Edit - Inara can reproduce this on Windows 7 SP1 64-bit (Build 7601) with a GeForce GTX 970.
