[Interest] QMessageBox not displayed when monitor is switched off

[Patrick ZAJDA]

Hello,

I am blind and use the attached bash script to switch my screen off and 
back on when needed.
I use Debian Bookworm with Mate desktop, NVIDIA as my graphic card.

I notice when screen is off, QMessageBox are note displayed at all when 
it worked with QT5.
I tried both with PySide6 and, thanks to an IA, using C++ with the same 
result so the issue is not related to Python.

I am lost in QT procedure to report this kind of issue.
Could someone explain me where and how should I report this kind of 
issue and firstly, could it be considered as a QT issue?

Best regards,
