The issue also exists in wayland

Comment 2 Nate Graham 2022-08-09 19:34:33 UTC

Are you using any screen scaling?

What happens if you manually maximize the panel using the "Maximize" button in its "more options" popup?

I have 100% scaling. The one pixel gap only appears on non-maximized panels.

Can reproduce on Wayland too.

Comment 5 Nate Graham 2023-09-18 21:04:54 UTC

Cannot reproduce anymore in Plasma 6 Wayland. So it's at least fixed there, if not earlier.
