Hmm, well, “works on my computer” is never a helpful comment but I have a heavily modified panel that I moved to the top with no issues.

I’m using the built-in task manager widget rather than a dock. Maybe that’s why?

Mind me asking what distro? And Wayland or X11? Also, which dock?

I’m using Wayland and Fedora (Plasma 6.4) and also had a good experience with NixOS (6.3, also Wayland).
