    Description

      Setting QT_DEVICE_PIXEL_RATIO=auto on X11 leads to several problems with multiple monitors:

      • Layouts are broken due to wrong fontMetrics
      • windows do not get repainted properly on screen change
      • menus do not work
      • we get X errors because the backingstore is the wrong size
      • windows sometimes end up on the wrong screen
