Screen goes on even Do No Disturb is enabled

It’s not the first time it happened, but this one I’m sure. Despite that the option Do Not Disturb is enabled, the screen went shortly on. As a notification is received.

I’m not sure it’s related, but I found these lines with journalctl:

invoker[6718]: WARNING: An inactive plugin is misbehaving - tried to show a window!
invoker[6718]: WARNING: requestActivate() called for  QQuickView(0x231acb00)  which has Qt::WindowDoesNotAcceptFocus set.

Patchmanager is installed, as angelfish and Android App Support is started by default.

Has someone saw the same phenomenon?

Small tip: If you only want logs from specific time range and in a file do as root:

journalctl -f --since="YYYY-MM-DD HH:MM:SS" --until="YYYY-MM-DD HH:MM:SS" > my_logs.txt
