Notification no longer appears in the Windows 11 notification center

[Davide Perini]

Ok,
thanks for the answer Aleksei,
now it's clear to me, I would say that it is now the Microsoft desired 
behaviour by default.

Another thing I noticed is that the icon on the notitification is now 
"corrupted" even if the icon on the tray icon is correctly shown.

... any idea on this?

Same icons worked perfectly well some "Windows updates" ago...

Non Java apps seems to work well,
is there something we can do to workaround this?

Thanks
Davide
