I'm building an overlay to display OBS stream stats over an full screen applications.
I've managed to achieve the visual part of it by setting the windows flags to: WindowStaysOnTopHint | FramelessWindowHint X11BypassWindowManagerHint)
The issue is that this window responds to the mouse (changes cursor to system one when hovered) and blocks the click actions. I found that WA_TransparentForMouseEvents and WA_TranslucentBackground will help, but it does not.
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtCore import Qt
app = QApplication([])
window = QWidget()
window.setWindowFlags(Qt.WindowStaysOnTopHint | Qt.FramelessWindowHint )#| Qt.X11BypassWindowManagerHint)
window.setAttribute(Qt.WA_TransparentForMouseEvents,True)
window.setAttribute(Qt.WA_TranslucentBackground,True)
window.show()
app.exec()
How can I make QtWindow to be transparent for the mouse and other events. In other works to act as a proper overlay.

The flag needed to be set is:
Qt::WindowTransparentForInputInforms the window system that this window is used only for output (displaying something) and does not take input. Therefore input events should pass through as if it wasn't there.
