I took a look at that macro and saw that in the case of OpenGL, it reads the contents of the frame buffer instead of making a new image. I wish I could have arranged to have the 'Allow Rerender' button grey out in the case of hardware rendering. I don't think it's possible to do that though. It also would have been nice to issue a warning if the situation could be detected. Oh well.
