    Description

      The touch points coordinates received by controls doesn't take into account the Device Pixel Ratio, the result is that, when the device pixel ratio is different than 1,  a slider follows the input coordinates when using the mouse, but doesn't when using touch . Same problem whith Flickable.

      No problem with Qt 5.15
