I have 3 monitors, and on each monitor, I have a Plasma panel at the bottom. When any notification pops up, I get 3 notifications on each monitor. I have a full fledged panel on each monitor with everything including task bar and system tray.
As you can imagine, this can get annoying pretty fast. Thanks to IRC and Bhushan Shah who proposed this solution, simply remove the system tray from the panels on the secondary monitors, and just keep the system tray on the primary monitor. This way, you will only get one-notification popup on each monitor instead of multiple ones!
To achieve this, first click on the hamburger icon in the panel to edit the panel. Then hover the mount over the system tray area where you get a popup like below that enables you to remove the system tray plasmoid.
