Normal display of branch:

nvim package.json

When I enter the src directory, the branch does not display properly:

cd src/
nvim App.tsx

Do not show branch

This will display the branch properly again:

nvim src/App.tsx

@DemoorBug Can you reproduce this with https://github.com/shadmansaleh/lualine.nvim ?

Can you reproduce it in just that folder or in any git folder ?

This file is considered deprecated by me . Switch to
https://github.com/shadmansaleh/lualine.nvim

and grab examples/evil_lualine.lua

That one is maintained see nvim-lualine/lualine.nvim#311 for details. Make proper issue reports in the repo.

I will not respond to issues here anymore .
