[Boot2Qt] Touched element appears on the cursor when trying to drag the icon

RPI 4 64 bit with Touch display (Waveshare 7")

Qt Creator 11.0.2

Steps to reproduce:

1. Open and run the example on Raspberry Pi4 with touch display (https://doc.qt.io/qt-6/qtwidgets-draganddrop-draggableicons-example.html)
2. Touch any icon and observe the mouse cursor 

Expected: The icon should not appear next to the cursor.

Actual: The icon appears next to the cursor. When the mouse is connected you can move the cursor, so that it is easily visible. When the mouse is disconnected the issue is still reproducible. 

NOTE: I'm not sure if this is boot2qt specific, but this example does not work on linux, so I cannot verify that with the touch display. 

Reproducibility:  100%
