(Sorry for duplicated)Serious Bug in computeshader on Vulkan(in both player and editor)

1.The simple computeshader(BugShader.compute) in attachment is to copy data from one buffer to another.It works fine and corretly on DX11 and OpenGLES3,only encounter bug on Vulkan.
When the data is simple native system type(int,float),it works fine,but if the data type is (float3,float4,int4..),it will fail.

2. Open the DemoScene in attachment and run on Vulkan(both Editor and Player have the same bug).
Left is the corret result.source and dest are same (using float), right is the bug error.source and dest are different (using float4).
I have posted a bug report:
fogbugz.unity3d.com/default.asp?1201840_mras0im6r5lh184f.

Has anyone here ecountered the same issue? any workaround?
Many thanks in advance.

 

[Closed]Using RWStructuredBuffer instead. Thanks Ramojus.
