Remarks
Warning
On Xbox 360, all render targets (including the back buffer) share the same memory. Because of this, the previous content of any render target is lost when the render target is changed with SetRenderTarget or when Present is called, which has the same effect as swapping the render target.
To preserve the data in a render target, it is necessary to resolve it, either with ResolveRenderTarget or ResolveBackBuffer. Just remember to resolve the render target before switching the render target to avoid losing data that you want to preserve.
