Unfortunately no real updates.... What I've been able to achieve: With picamera2, one can intercept every newly generated frame with a callback, modify+copy it into a numpy array and then memmap into the framebuffer. This way it is shown on both screens and another ouptut can be placed on top of it in the output to the first monitor. This actually works with > 30fps when both monitors are 1920x1080. The catch is, that at the moment I cannot get vsync to work and tearing is visible in the memmapped preview, when the camera moves quickly.
