found and solved one small problem, when zooming the image node, especially with the height and width changing at the same time

QPainter::begin: Paint device returnd engine == 0,type:2 QPainter::begin: Painter must be active to set rendering hints.

NodeGemetry.cpp QPointF NodeGeometry::widgetPosiont() const

return QPointF(_spacing + portWidth(PortType::In), (captionHeight() + _height - validateHeight() - _spacing - w->height())/2.0);

return QPointF(_spacing + portWidth(PortType::In), (captionHeight() + _height - w->height())/2.0);

w->height() is int, but captionHeight(), _height, validateHeight(),_spacing are unsigned int , this cause the problem.

I do it like this: return QPointF(_spacing + portWidth(PortType::In), ((int)captionHeight() + (int)_height - (int)validateHeight() - (int)_spacing - w->height())/2.0);

return QPointF(_spacing + portWidth(PortType::In), ((int)captionHeight() + (int)_height - w->height())/2.0);

it works well
