System tray is full of notifications and timeout doesn't seem to have any effect

[Dashyyy]

OS: Win10
The notifications that are being created stay in the tray and in the notification bar unless I open up the tray and wait a few seconds.
Changing the "timout" parameter doesn't seem to have any effect on how long the notification is shown nor does it fix said issue.

I don't know if this behaviour is intentional or not but if it ain't so I have found a possible fix #751

I have this issue, whereby notifications are spamming the system tray. I tried adding the line from your possible solution to balloontip.py but it didn't seem to prevent it 😖
