Hello,
While developing with PySide6, I noticed it is not possible to display a
QMessageBox while screen is turned off using xrandr.
If the QMessageBox is displayed with no parent window E.G. when the
application starts the app simply freezes and the only way to leave this
state is to kill it.
No error is displayed in the terminal, if a QMainWindow or QDialog is
displayed you will still be able to use it but when closing the last
displayed interface, the application will still run in background.
I opened this bug report:
https://bugreports.qt.io/browse/QTBUG-132149
Hop this helps,
