Custom cursor is incorrectly sized if Override high DPI scaling is set

If the Override high DPI scaling behavior is set to System in the application's Compatibility settings, any custom QCursor loaded from a pixmap draws too small on a monitor with DPI scaling above 100%.  The same cursor draws correctly with different monitor DPI scalings if the Override is not done.  

We are setting these:

QApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
QApplication::setAttribute(Qt::AA_UseHighDpiPixmaps);

The cursor is being set like this:

QPixmap pixmap(cursorPath);
pixmap.setDevicePixelRatio(1.75);
return QCursor(pixmap);
