    •  f5b9cdbb0844dd149d9b945b28da42d56977f844 (qtbase/5.6.0, 10.2.2016, 5.6.0)

    Description

      1. Move any window over the window which uses QT_SCALE_FACTOR - you will see lines (Unwanted_lines.png).

      2. Any native widget is not visible (in Native_widget.png the push button is a native widget)!
