OK thanks, it’s good to know the expected behaviour. It certainly works that way on Mac, but I’m reasonably certain that it is not working that way on Linux (at least on the most recent version available on raspberry pi).
Images attached that show the behaviour on Linux - I launch the simple random patch twice on Linux and it produces the exact same stream of numbers. So perhaps this is a bug that I should file? Perhaps someone else can confirm?
