I do think that robot should emulate what you can manually do with a mouse/keyboard, and since we can't interact with a window offscreen normally robot shouldn't be able to do so either. Also, since mousePress and mouseRelease can't be done offscreen either because of the checkMousePos() call anyway, it doesn't make sense to keep mouseMove behavior as is as the only mouse function to be able to go offscreen. ------------- PR Comment: https://git.openjdk.org/jdk/pull/22781#issuecomment-2632364505
