class dialog(QDialog, AcrylicWindow):
    def __init__(self):
        super().__init__()
        setTheme(Theme.DARK)

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        setTheme(Theme.DARK)
        container=QWidget()
        layout=QVBoxLayout()
        self.setStyleSheet("background-color: #303030;")
        button=PushButton("open new window")
        button.setStyleSheet("background-color: red;")
        button.clicked.connect(self.newDialog)

        container.setLayout(layout)
        layout.addWidget(button)
        self.setCentralWidget(container)

    def newDialog(self):
        newdialog=dialog()
        newdialog.show()

app = QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec())

Expected behavior Stylesheet of main window should be left alone.
