Is the first window that you see a black one that animates from the application icon to fill the screen and has the sound effect of an opening window attached to it? If so, it's just a fake window displayed by the window manager (hildon-desktop) that will stay there for some seconds (the idea being that your application is fast enough to open a window, which will then replace that fake window). The fake window makes the user feel that the application startup is instant (via the animation) while giving the application a second or two to really start up and show a window. You can "fix" this by doing all the time-consuming operations *after* you have created and shown your window. You can usually populate your window with contents even after it has been shown, so that would be a good idea to do in that case. You can do this using single-shot QTimer, so that the main loop gets enough time to really show and draw the initial window. HTH.
