mouse pos() returns wrong position

[FlyDoodle]

Hello !,
So i have a problem getting pos from the point where i click on the mouse ( using right click )
check this video :
https://streamable.com/cjo0d
- Here you can see at the beginning i try moving him around using right click on the mouse and it's all working fine. But when i reach the land or at least when im near it the returned position is completely different as i expected it to be...
you can see when i print the character current position and the positioning of the mouse ( when i press right click ) in the debug console it gives me wrong coordinates ( from the mouse ) and i don't know why... Sea and Land are two different QGraphicsPixmapItems both have their own class, so maybe it has to do something with that ?
Here is the main class code:

In the Land and Sea class i just setPixmap to the image, put them into the scene,set position and that is it.

And i have one more question, how do i make a player stop when he reaches his destination ? i was thinking about making an QGraphicsRectItem whenever i press a right button and then checking if player has collided with that item and when he does he stops and then that item gets deleted or is there a better and easier way to do that, cause comparing mouse pos() and player pos() is not working.

Any kind of help or advice is appreciated !!!
