It seems to me that something goes wrong when changing resolutions, this is especially annoying with applications defaulting to 640x480, and it seem to involve the top left corner of the screen...
The impression I get from your description and screenshots is that setting the display mode actually work fine, but the application window is never resized from its original size.
