BackgroundPlotter doesn't show when use plotter.show()

[zhengliuer]

Hi, this is my code

import pyvista as pv
from pyvistaqt import BackgroundPlotter

p = BackgroundPlotter(show=False)
p.show()

I set the BackgroundPlotter show=False, according to the doc, after I call plotter.show(), it should show, but not.

OK, I use plotter.app_window.show() and it shows again. But when I call it again after closing the window, it's got nothing like this
