If you want to narrow it down to the actual perpetrators, I believe it's all down to 2 widgets that are adding their own Layout with margins.
They both happen to have a QGridLayout, so you could test for that and only change the margins when you come across a QGridLayout. http://pastebin.com/UX4idRBC Still hacky, but it might help you narrow it down to the actual perpetrators.
