Problem with the arrival of messages

Every message i get appears in the center of the screen when it should appear in the corner

If you’re on X11, it sounds like 481736 – On X11, Notifications pop up in the middle of the screen after being away from pc for a while.

I had this problem too. Dialogs and messages were all over the place. It seemed to resolve itself when I adjusted the “Hide After” setting to 6 seconds from 5 in the Notifications section of Settings. It seems like the config was not updating until then. I have not had an issue since. I am using X11.
