SetRenderTarget problem

[SubPixelPerfect]

Hi, I’m working on a post effect

and for that i need to render set of meshes to texture with ZTest LEqual to create a mask

here is a sphere rendered to separate texture

so i’m creating new RenderTexture and setting it as active color buffer while leaving depth buffer unchanged
rendering what i need and resetting render target

and everything works perfect

but when i’m enabling Direct3D in player settings and enabling anti-aliasing in quality settings
i’m getting an error:

ArgumentException: Graphics.SetRenderTarget called with depth RenderBuffer from screen and color RenderBuffer from RenderTexture
UnityEngine.Graphics.SetRenderTargetImpl (RenderBuffer colorBuffer, RenderBuffer depthBuffer, Int32 mipLevel, CubemapFace face, Int32 depthSlice) (at C:/buildslave/unity/build/Runtime/Export/Graphics.cs:189)
UnityEngine.Graphics.SetRenderTarget (RenderBuffer colorBuffer, RenderBuffer depthBuffer) (at C:/buildslave/unity/build/Runtime/Export/Graphics.cs:225)

here is my code:

void OnRenderImageTest0(RenderTexture source, RenderTexture destination){
        // create new render target
        RenderTexture rt = RenderTexture.GetTemporary(_camera.pixelWidth, _camera.pixelHeight);
        rt.Create();
        RenderBuffer tmp = Graphics.activeColorBuffer;

        // change render target
        Graphics.SetRenderTarget(rt.colorBuffer, Graphics.activeDepthBuffer);

        ...
        // render meshes
        ...

        // reset render target
        Graphics.SetRenderTarget(tmp, Graphics.activeDepthBuffer);
        rt.Release();
    }

is it a bug or i’m doing something wrong?
is there any way to do that on Direct3D with enabled anti-aliasing?

here i’ve found that

in D3D10 you cannot share a depth surface between render targets of different sizes.

But in my case size is equal.

unity documentation says:

Unity - Manual: Cameras and depth textures

When implementing complex Shaders or Image Effects, keep Rendering Differences Between Platforms in mind. In particular, using depth texture in an Image Effect often needs special handling on Direct3D + Anti-Aliasing.

In some cases, the depth texture might come directly from the native Z buffer. If you see artifacts in your depth texture, make sure that the shaders that use it do not write into the Z buffer (use ZWrite Off).

ok, I have ZWrite Off

more from docs:

Unity - Manual: Writing shaders for different graphics APIs

Vertical Texture coordinate conventions differ between two types of platforms: Direct3D-like and OpenGL-like.
…
When you use Image Effects and anti-aliasing, the resulting source Texture for an Image Effect is not flipped to match the OpenGL-like platform convention. In this case, Unity renders to the screen to get anti-aliasing and then resolves rendering into a Render Texture for further processing with an Image Effect.
…
…
…
Depth (Z) direction differs on different Shader platforms.
…
If you are fetching the depth (Z) buffer value manually, you might want to check the buffer direction.

this is clear, but what i can do in my case?
