Popup notifications not showing at all in KDE5 session

[Serhiy]

I've tried setting popup notifications for various events in systemsettings5 and none of them are showing up. Also, none of these commands display anything and return exit status 0:

notify-send 'text'
kdialog --passivepopup 'text' 5
qdbus org.kde.knotify /Notify event "event" 'app' "(" ")" 'title' 'text' 'pixmap' '' 5 0

If I set the only panel that contains the system tray to autohide and log in with that state all popup notifications become just a blinking for fractions of a second rectangles in the top left corner.

Reproducible: Always

Steps to Reproduce:
1. Set the main panel to autohide.
2. Log out and log in.
3. Trigger/Send any popup notification.

Actual Results:
Notifications appear just for a couple of frames in the top left corner regardless of their location settings.

Expected Results:
Notification visible for set period of time in the desired screen corner.

Panel is on the left in case it matters. Notification reappear until the end of current session if the autohide option is toggled.

Thanks for the report

Works fine here, which Plasma version are you using?
