I've had a good look into this on multiple occasions but never quite got to the bottom of it…
The problem seems to be (at least partially) that AbstractNotationPaintView::dragMoveEvent doesn’t receive a call. If you monitor the event types arriving at AbstractNotationPaintView::event, in Qt5 we receive repeated DragMove events while in Qt6 we get repeated DragEnter and DragLeave events instead.
The Qt code that determines which event type to send is in deliverDragEvent. In Qt5 this method is in qtquickwindow.cpp, in Qt6 this is in qtquickdeliveryagent.cpp. Our answer probably lies in there somewhere...
