[Feature Request]: Unable to remove background

[titanilham]

What?

I tried:

highlight StatusLine guibg=NONE ctermbg=NONE
highlight StatusLineNC guibg=NONE ctermbg=NONE
highlight BufferLineFill guibg=NONE ctermbg=NONE
highlight BufferLineSeparator guibg=NONE ctermbg=NONE
highlight BufferLineSeparatorSelected guibg=NONE ctermbg=NONE
highlight VertSplit guibg=NONE ctermbg=NONE

and:

require("bufferline").setup {
  options = {
    numbers = "none",
    close_command = "bdelete! %d",
    right_mouse_command = "bdelete! %d",
    left_mouse_command = "buffer %d",
    diagnostics = "nvim_lsp",
    offsets = {
      {
        filetype = "NvimTree",
        text = "Explorer",
        padding = 1,
      }
    },
    show_close_icon = true,
    show_buffer_close_icons = true,
    separator_style = "thin",
  },
  highlights = {
    fill = {
      guibg = "NONE",
      ctermbg = "NONE",
    },
    background = {
      guibg = "NONE",
      ctermbg = "NONE",
    },
}

This is what I look like:

I would like to remove the background of this line

Why?

Line worsens view
