Wrong Touch Coordinates

When I touch left side of the button carefully, it shows X coordinate as 592 (Debug "X") but it should have been 614 (TouchGFX "X"). In similar manner, when I touch top side of the button carefully, it shows Y coordinate as 397 (Debug "Y") but it should have been 377 (TouchGFX "Y"). Where does this coordinate difference come from between real application and TouchGFX Designer? Might there be any offset? If yes, is there any solution for this? FT5x06 touch controller is being used on my custom PCB but I am using FT5336 driver that is published by ST for stm32f746g-disco dev-board. So... Using FT5336 driver in FT5x06 ic might be a problem? Display dimensions 800x480. Thank you!

Does someone know why I have this problem?
