Qt 5.3.1 here.

There're actually more issues - nevertheless both steps are (theoretically) required.
Creating the platform window *should* apply the widget size - I suspect a QWidget QPA bug here.

Creating the window handle, then restoring the window handle and then explicitly copying the QWindow size should work, though.
