    Description

      This simple script is supposed to create a modal window without borders neither title:

      import sys
      from PyQt5.QtWidgets import QApplication, QDialog, QLabel
      from PyQt5.QtCore import Qt
      
      app = QApplication(sys.argv)
      d = QDialog()
      d.setModal(True)
      d.setWindowFlags(Qt.WindowStaysOnTopHint | Qt.FramelessWindowHint)
      
      d.setMinimumWidth(400)
      d.setMinimumHeight(400)
      d.setMaximumWidth(400)
      d.setMaximumHeight(400)
      
      QLabel('Hello world', d)
      d.show()
      sys.exit(app.exec_())
      

      But the borders are still here (see image: https://ddgobkiprc33d.cloudfront.net/43f52064-21d5-4d50-b678-c59421d45ff6.jpg).

      Note that the borders disapears correctly when I run the application with QT_QPA_PLATFORM="xcb".

      It seems that this is not an issue with Sway

      I wrote the equivalent program in C++ and I get the same behavior, so it's not a problem with PyQt.
