Maybe some fpc troubles? We are calling translate so:
TQtDeviceContext(DC).translate(P.X, P.Y);
where P.X and P.Y are integers but translate arguments are doubles. So
maybe fpc wrongly converts integers to double? Can you check what do you
get in TQtDeviceContext.translate. I mean arguments dx and dy.
Btw, what fpc version do you use?
Best regards,
