RenderWindow crash on dual monitor (laptop w/ external)
« on: March 03, 2010, 06:52:46 pm »
I use my laptop with an external monitor in my office. I use both screens (dual monitor setup) with the external monitor as the primary display. The following code crashes, sometimes taking the whole machine with it. I do not experience problems using a single monitor or using two monitors with the laptop screen set as the primary display.

Any help would be appreciated.

Code: [Select]
 sf::RenderWindow canvas(sf::VideoMode(), "Dual Crasher", sf::Style::Fullscreen);
  sf::Color canvasColor(192,192,192);
  // Start game loop
  while (canvas.IsOpened())
    // Process events
    sf::Event Event;
    while (canvas.GetEvent(Event))
      // Close window : exit
      if (Event.Type == sf::Event::Closed)

      // Escape key : exit
      else if (Event.Type == sf::Event::KeyPressed)
        if (Event.Key.Code == sf::Key::Escape)

    // Draw background

    // Finally, display the rendered frame on screen

RenderWindow crash on dual monitor (laptop w/ external)

SFML has no real support for multiple monitors, so I guess that this kind of things can happen. Anyway, I have no idea what to do to fix that, you'll probably have to wait until I implement a robust support for multiple monitors.

What you can do (if you really want to help) is debugging the application and see where it crashes in SFML source code.
