only one of the subplots work on 4k monitor

[sunilpulinthitta]

I can move the app to 2k monitor and all subplots become responsive, but as I move it to the 4k monitor all except one works. I also ran the code on a MacBook Air and had the same issue as it had a high resolution screen.

import sys
import os
from qtpy import QtWidgets
import pyvista as pv
from pyvistaqt import QtInteractor, MainWindow

class MyMainWindow(MainWindow):

    def __init__(self, parent=None, show=True):
        QtWidgets.QMainWindow.__init__(self, parent)

        # create the frame
        self.frame = QtWidgets.QFrame()
        vlayout = QtWidgets.QVBoxLayout()

        # add the pyvista interactor object
        self.plotter = QtInteractor(self.frame, shape=(2, 2))
        vlayout.addWidget(self.plotter.interactor)
        self.signal_close.connect(self.plotter.close)

        self.frame.setLayout(vlayout)
        self.setCentralWidget(self.frame)

        self.plotter.subplot(0, 0)
        self.plotter.add_mesh(pv.Sphere())
        self.plotter.subplot(0, 1)
        self.plotter.add_mesh(pv.Cylinder())
        self.plotter.subplot(1, 0)
        self.plotter.add_mesh(pv.Cube())
        self.plotter.subplot(1, 1)
        self.plotter.add_mesh(pv.Cone())

        if show:
            self.show()


if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    window = MyMainWindow()
    sys.exit(app.exec_())
