graph_tool graph_draw vertex text box margins vertex overlaps

Question

Im trying to output a graph created using python graph_tool library to a png file. The final result is that the drawn graph vertexes overlaps. I realized that the problem is when i put text on the vertexes or edges, is like the margins of the text box are too big.

size = 4000
v_size = size/my_graph
e_pwidth = v_size/10
graph_draw(my_graph, vertex_shape='square', vertex_text=my_graph.vp.inst_str, vertex_size=v_size, output_size=(size, int(size*1.5), vertex_font_size=e_pwidth, vertex_aspect=1.5, edge_pen_width=e_pwidth, edge_text=my_graph.ep.edgelabel, output="f.png")

It will output something like:

Look at the distance between the text and the borders of the vertex, i can't get to reduce that distance.

I think i've found a way. The thing is that when you set a text property to the vertexes it increases the size of vertexes to fit the text in, however if you set the property vertex_text_position to any negative value other than -1 it will not resize the vertex and then you can set the size of vertex you want.
