qt5base-lts/tests/auto/widgets/graphicsview/qgraphicsscene/tst_qgraphicsscene.cpp
Friedemann Kleint c2aaa9e18e tst_QGraphicsScene: Pass on High DPI screens 
The test requires High DPI scaling to be disabled since it
captures widgets.

Turn it off initially and introduce a member variable
containing a suitable size depending on the screen to make the
test pass on High DPI screens without violating minimum window
widths on Windows.
