Plotter and QtInteractor are producing different results when reset_camera is None

Thanks for reporting, I'll take a look later today 👌

I hope to reproduce it at least 😅

I can reproduce the inconsistency:

PyVista	PyVistaQt

PyVista

import pyvista as pv

from pyvista import examples


def cell_picking(picked_cells):
    reset_camera = None  # change here
    plotter.add_mesh(
        picked_cells,
        color='pink',
        style='wireframe',
        name='picked_cells',
        reset_camera=reset_camera
    )
    plotter.add_point_labels(
        picked_cells.cell_centers(),
        'Spatial Cell Data',
        name='picked_cell_labels',
        reset_camera=reset_camera
    )


grid = examples.load_uniform()

plotter = pv.Plotter(shape=(1, 2))
plotter.subplot(0, 0)
plotter.add_axes()
plotter.add_mesh(grid, color='white', show_edges=True)
plotter.enable_cell_picking(grid, cell_picking)
plotter.subplot(0, 1)
plotter.add_axes()
plotter.show()

PyVistaQt

import sys

from PyQt5.QtWidgets import QApplication, QMainWindow

from pyvista import examples
from pyvistaqt import QtInteractor


class Viewer(QMainWindow):

    def __init__(self):
        super(Viewer, self).__init__()

        grid = examples.load_uniform()

        self.plotter = QtInteractor(self, shape=(1, 2))
        self.plotter.subplot(0, 0)
        self.plotter.add_axes()
        self.plotter.add_mesh(grid, color='white', show_edges=True)
        self.plotter.enable_cell_picking(grid, self.cell_picking)
        self.plotter.subplot(0, 1)
        self.plotter.add_axes()
        self.plotter.show()
        self.setCentralWidget(self.plotter)

    def cell_picking(self, picked_cells):
        reset_camera = None  # change here
        self.plotter.add_mesh(
            picked_cells,
            color='pink',
            style='wireframe',
            name='picked_cells',
            reset_camera=reset_camera
        )
        self.plotter.add_point_labels(
            picked_cells.cell_centers(),
            'Spatial Cell Data',
            name='picked_cell_labels',
            reset_camera=reset_camera
        )


if __name__ == '__main__':
    app = QApplication(sys.argv)
    viewer = Viewer()
    viewer.show()
    viewer.resize(1024, 768)
    sys.exit(app.exec_())

Issue seems to be related to resetting the camera.
