screenshot secondary screen

I have two screens and on the second screen I set the taskbar the same as on the first.
The first taskbar is okay, but the window bar of the second taskbar shows so much space to the next plasmoid in the middle. 

1. create empty taskbar on the secondary screen
2. configure it the same as the taskbar of the primary screen

window bar of each screen has different space to the next plasmoid

no space to the next plasmoid on both screens

You might have a separator more in the taskbar with the issue between virtual desktop indicator and task list.
Try editing your task bar and remove the separator plasmoid between.

No there's no additional spacer between.

All right thanks to your screen cast we can see the pinned icons widget is too wide compared to how it should be.

From the duplicate bug report:  

> I think the problem is `launcherLayoutTasks` in the layout code, which always adds one or more spaces the size of a regular task even when (as in my example) part of it are only launchers.
Comment 7 Natalie Clarius 2023-07-31 21:58:29 UTC
Without launchers the problem does not occur.

Use a GridLayout for taskbar layout

The current javascript layout code is very buggy and error prone,
The normal layouting mechanism of GridLayout is much more reliable
and does for faster and more readable code
