The problem is this line:-
> g2d.setTransform(new AffineTransform());
in your code.
Swing specifies a translation on its graphics during repainting
of damaged areas.
By using "setTransform()" you just completely over-rode that
and now Swing will repair the wrong area.
you can translate, rotate etc .. but do not use setTransform()
