The GL_EXT_multisampled_render_to_texture spec explicitly allow reading from these FBOs. "Similarly, for ReadPixels: 'An INVALID_OPERATION error is generated if the value of READ_- FRAMEBUFFER_BINDING (see section 9) is non-zero, the read framebuffer is framebuffer complete, and the value of SAMPLE_BUFFERS for the read framebuffer is one.' These errors do not apply to textures and renderbuffers that have associated multisample data specified by the mechanisms described in this extension, i.e., the above operations are allowed even when SAMPLE_BUFFERS is non-zero for renderbuffers created via Renderbuffer- StorageMultisampleEXT or textures attached via FramebufferTexture2D- MultisampleEXT."
