Expected behavior

Colorscheme should apply correctly

Actual behavior

It doesn't

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "catppuccin/nvim",
  "vim-airline/vim-airline",
}

vim.g.airline_powerline_fonts = 1
vim.g.airline_theme = "catppuccin"

require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("catppuccin")

Seems like an alacritty issue.

Seems like an alacritty issue.

The same occurs with kitty and konsole.

Can you elaborate the expected behavior, I'm not sure what's wrong?

[Aniamon]

The characters at the right are not using the colorscheme.
