Delphi 10.4.1 Draws crookedly, the lines go somewhere above

Let's try to draw a straight line from point A to point B.

Put a button on the form and write in the onClick handler:

TPoint = record
   x, y: Integer;
end;

procedure DrawLine(A, B: TPoint);
begin
   Form1.Canvas.MoveTo(A.x, A.y);
   Form1.Canvas.LineTo(B.x, B.y);
end;

A.x: = 0;
A.y: = 0;
B.x: = 100;
B.y: = 10;
DrawLine(A, B);
