Plotter.clear() function could not work correctly.

Hi Marco,
After upgrading Vedo to 2022.4.2 and VTK to 9.2.5 several days befor, the Plotter.clear() function could not work correctly.
There are three line-meshes created by Lines and one face-mesh created by Mesh in my model.
One line-mesh could not be cleared by the Plotter.clear() function like it did before and here is the errors. (self.plt = Plotter(axes=4))
Do you know why? Is there any other ways to clear all actors in the plot? Thanks!!

Hi Marco,
I added the deep=True,render=True the clear() function works correctly.
Pls forget the question.
Thanks.
