Short description of error
While rendering in a separate window, you can go back to main window, open preferences and boom, preferences are opened in the render window. You can see the progress bar on windows taskbar still going on, everything is being computed, but you are not going to get the full image. You can open the Rendering tab and see your render as 'finished' even though it's still computing. After it finishes - it does not update the image. It's in the state from the moment of opening settings.
