Description jnmaloney 2015-06-29 06:24:29 UTC 
I'm still experiencing this bug on Windows in 2.0.4 RC2.

https://bugzilla.libsdl.org/show_bug.cgi?id=2705

Using the code:

  SDL_SetRenderTarget(m_renderer, m_targetTex);
  int readResult = SDL_RenderReadPixels(m_renderer, NULL, SDL_PIXELFORMAT_ARGB8888, pixelData, pitch);
  SDL_SetRenderTarget(m_renderer, NULL);

The actual pixel data is grabbed from the backbuffer, and not the render target.
