Unsolved Return back from fullscreen on Mac

[Unick]

Hello.

Today i faced with one problem with Qt 5.5 on Mac. If i calls showNormal right after showFullScreen, it does not work correct. I stay on separate desktop and it is gray. Looks like widget is stay full screen. Here is my test code:

int main(int argv, char **args)
{
QApplication app(argv, args);
QWidget window;
window.show();
window.showFullScreen();
window.showNormal();

return app.exec();
}

Is it bug in Qt or i do something wrong?

Why should the widget be closed?
You do not close it.
After

window.showNormal();

is it still in full-screen mode or just maximized?

@jsulm Sorry, i was i little wrong. Widget is full screen after showNormal(). I have the same problem if i call hide instead of showNormal.
