libkf5notifications5 Version: 5.18.0-0ubuntu1
There are some notifications (eg. those that are triggered by Opera) that do not disappear automatically but stay visible until they get clicked.
Others disappear after a few seconds.
Actually it would be nice if there would be the possibility to configure the notifications in terms of duration, stickiness etc on a per process base (like snarl on windows).

I am seeing this as well.
Info Center gives:
Operating System: Fedora 33
KDE Plasma Version: 5.20.3
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1

Memory: 23.1 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 620
Its not consistent , if I clear all notifications sometimes things sent with timeout do go away, sometimes things get stuck and then they all pile up. This even happens with kdialog with --passivepopup <msg> 3
If I clear all notifications, then e.g. "/usr/bin/kdialog --passivepopup "%subject from %sendername" 3" works again and messages stop piling up.
I do wonder if its Firefox google chat pinned tab that is not timing out that then causes everything to pile up behind it.
