I'm not sure whether all the issues I bring up on this JIRA are bugs or just a case of things rendering differently on EEP in an expected way, but thought it worth filing this any way to be looked at.

Steps To Reproduce

• Go to location http://maps.secondlife.com/secondlife/Fluffy/203/159/17 and look out over the water.

• Compare how the scene renders on EEP viewer Second Life Release 6.4.0.538312 (64bit) and default release viewer https://releasenotes.secondlife.com/viewer/6.3.7.535996.html with both ALM enabled & ALM disabled.

  Observed Behaviour

• Default release, toggling ALM: https://gyazo.com/e2f8a6ec3a20bc0ba509add834ccf453

• EEP toggling ALM: https://gyazo.com/332445951fc4eb2e806d033347ce8802

• My gifs are taken with graphics settings set to Ultra & with Ambient occlusion & shadows disabled and then toggling ALM.

Shading of In-region water & void Linden water

• Observe how on default release, with both ALM enabled & ALM disabled, there is no marked difference in the shading of the water between the in-region Linden water and the void Linden water. The transition is smooth & you cannot see where the in-region water changes to the void water.

• Observe that on the EEP viewer, there is a marked difference between the shading of the in-region water and the void water.
  This difference is fairly noticeable when ALM is enabled but it's extremely noticeable when ALM is disabled.
  The line separating the in-region water & the void water is always noticeable & it looks extremely ugly especially when ALM is disabled & the void water turns a bright neon green.
