[Shadows][Quality] There is 1px white border in Forward+MSAA (because of Screenspace Shadow Collect pass)
When using standard MSAA in the Unity quality settings, with forward rendering, I'm getting a 1px white border between my object and its shadow. This is on a Radeon 5850. Changing the shader between diffuse or specular makes no difference, and neither does implementing the specular shader fix which some people have posted on the forums for a similar issue (adding o.Normal = fixed3(0,0,1);). Using no AA, FXAA etc, are all OK and have no issues.
To reproduce:
1 Open attached project
2 Open scene "Scene"
3 Look at the chassis_small object
If using no Anti Aliasing - it works fine.

I think that this error is caused, because the anti aliasing process uses the unshaded background to smooth the edges. Shadows are ignored in this process. Try a scene where a cube is on a red ground and a spotlight. When you now look at the cube, you can see a red line between the cube and the shadow.
It's a problem with many graphic cards, I use the AMD 7950 HD
