'Transparent PyQT5 window does not show over fullscreened application

I am currently trying to make an overlay for games using a transparent PyQT5 window. My current code:

class MainWindow(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)
        self.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint | QtCore.Qt.FramelessWindowHint | QtCore.Qt.X11BypassWindowManagerHint)
        self.setGeometry(QtWidgets.QStyle.alignedRect(QtCore.Qt.LeftToRight, QtCore.Qt.AlignRight | QtCore.Qt.AlignTop, QtCore.QSize(round(screeninfo.get_monitors()[0].width/3), round(screeninfo.get_monitors()[0].height/5)), QtWidgets.qApp.desktop().availableGeometry()))
        self.setAttribute(QtCore.Qt.WA_TranslucentBackground, True)
        self.show()

Except it doesn't show over fullscreened applications (like games). Is there an attribute I can set that can enable it to show on top of fullscreened applications as well?
