QWidget::move works differently before window is created than after.

When I call QWidget::move before showing the window it seems to be placed where I expect it. After the window has been displayed, if you call move with the same coordinates, it shows up on a different place on the screen.

When you run the example provided, the first time you hit a key, the window shows up at 21,21. The second time, it should show up at 22,22, but it shows up at 22,33. Each subsequent button press moves it down and over 1 as expected.
