    • Windows

      In my setup I have the main HD display scaled at 125% and the HD display on the left scaled at 100%.

      I have a QQuickWindow placed on the left screen and a timer that increases its x coordinate so that eventually the window will move to the main display.

      If I use the function QQuickWindow:setPosition, I see a vertical jump and the warning "Unable to set geometry...." when the window crosses the screen,

      If I set the position using the Window api SetWindowPos, everything works fine
