Did that - but umbrello did not pick up the changed value.
So I just modified the initial value of m_origin in the LayoutGenerator
constructor.
And now at least I can see all classes on the diagram.

I did a little debugging and I see some small values for r.x() but larger
values for r.width() - which explains why the x coordinate turns out negative
when m_origin is not large enough.
Example: m_origin.x() = 50, r.x() = 20 , r.width() = 200
