SSAO Issue - Bad reflection on water

[NumeriChunk]

Hello,
I have an issue about SSAO reflection on water.
As you wan see on this video [i.imgur.com]
A shadow of the characters is appearing on the water's reflection.

There is anyone can help me to understand and fix it ?

Thanks.

Are you sure that the issue is a result of ambient occlusion? (What happens if you disable it?)

Hello,
Yes I'm sure. On this other video [i.imgur.com], I've deactivated Ambient occlusion, and the reflection is "natural".

What does it look like if you enable the "Show AO" option? (This will show a grey-scale image of the ambient occlusion "pass".)
And what map is it? (Please link to where you downloaded the map from, as well as let us know the name if the download has multiple maps.)

If I enable the "Show AO", we cant see the reflection in the water ( video [i.imgur.com])

This is a map I've created. I use the : "liquids/boathouse_water" texture as water.
I've put an "env_cubemap" with "water_lod_control".

I don't seem to have that material. Please open it in a raw text editor (such as Notepad or Notepad++), select everything in it, copy the text, and paste it here.

While I don't really know much about water in Source, there's nothing there that seems immediately obviously-wrong to me. So, I'll just come with a silly suggestion and two silly questions now.

Make sure that there's some map geometry (other than the skybox) below the water. (I can't tell whether or not there is in your videos.)
Do you get the same issue in another map (one that you have not made yourself) that uses the same water surface material?
Do you get the same issue with the water of CTF_2Fort (a map that's included with Source Filmmaker by default; the water is near the middle of the map, below the bridge between the red and blue halves of the map)?

[NumeriChunk]

I've re check the map geometry but nothing wrong.

I have the same issue with this map.

I have try 2fort map but, there is no reflection on the water so I cant check if I have the same issue.

This sounds suspicious. So I should probably have asked about this earlier... What CPU, GPU(s), amount of RAM, and operating system does your computer have?

To find out what CPU, amount of RAM, and operating system your computer has, press the Windows key, search for and open "dxdiag", and look at exactly what it says beside "Processor", "Memory", and "Operating System" in the "System" tab.

To find out what GPU(s) your computer has, open the Control Panel, change the drop-down "View by" selection list to "Large icons" or "Small icons", click "Device Manager", expand the "Display Adapters" list/group, and look at the exact names of all items in that list/group.
