Nodes label get duplicated every time show/render are called #733

cerlumi commented 12 months ago

Testing the version 4.0.0-beta, I tried to create a simple graph.

The first display/rendering of the graph is correct, but every subsequent call to show or render adds an extra duplicated label.

Code to reproduce the issue.

from ete4 import Tree

t = Tree()
t.populate(3)
t.show()

# closing the window and running again
t.show()

# closing the window and running again
t.show()

# closing the window and trying to render an image
t.render('render.png')

Output: show_1 show_2 show_3 render

Hi in ete4 version, we no longer maintain with PyQt, which means we don't update in show(), render() method. Instead we use explore() in ete4 to visualize the tree
