Two modelines in Emacs 29.4

[root42]

Since Emacs 29.4 (maybe earlier) I have two nano-modelines -- one at the top, one at the bottom of my window. I can use hide-mode-line package to hide the lower one, but I actually want the nano modeline to be at the bottom, so this is only a workaround.

This happens even with a minimal configuration. But also with my config, where I have written my own nano-modeline hook (e.g. for showing the git branch).

It seems you can also work around it by disabling the modeline this way:

  (setq mode-line-format nil)

There is an open merge request which does something similar.

It's weird and the modeline should be only at one place. And the way to disable the modeline is exactly the code you wrote. If you want to make it the default, you can also write (setq-default mode-line-format nil)
