No highlighting in markdown/text/vim files using lazyvim

[Grolaf]

Dear community,

I've recently switched from my old lua config to Lazyvim. Before, I used the same gruvbox plugin, and I had no problem with highlighting in markdown/text/vim files. I used treesitter, the same plugin that LazyVim uses.

I honestly don't know if the problem relies on gruvbox, Lazyvim, treesitter, or maybe the Kitty terminal.

But if I switch from gruvbox to tokyonight colorscheme, then the highlighting works well in the same files ! This is why I'm wondering about a bug in gruvbox plugin.

Here are the screenshots with gruvbox and tokyonight colorschemes. I've just switched using :colorscheme tokyonight

In other filetypes, there is no problem (python, typescript, c, c++....)

Here is my config :

return {
  -- add gruvbox
  { "ellisonleao/gruvbox.nvim" },

  -- Configure LazyVim to load gruvbox
  {
    "LazyVim/LazyVim",
    opts = {
      colorscheme = "gruvbox",
    },
  },

}

This is by the way the recommended configuration for LazyVim (https://www.lazyvim.org/plugins/colorscheme)

Does anyone have/had the same problem ?

Thank you a lot for answering me,
Antoine.
