Alacritty with Ueberzug in Wayland remains blank

I am using Sway on Arch Linux and compiled ueberzugpp from source.

This is my ueberzugpp config:

{
  "layer": {
    "silent": false,
    "use-escape-codes": false,
    "no-stdin": false,
    "output": "wayland"
  }
}

This to what I have changed the minimal example to:

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--branch=stable",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

require("lazy").setup({
  {
    "3rd/image.nvim",
    event = "VeryLazy",
    dependencies = {
      {
        "nvim-treesitter/nvim-treesitter",
        build = ":TSUpdate",
        config = function()
          require("nvim-treesitter.configs").setup({
            ensure_installed = { "markdown" },
            highlight = { enable = true },
          })
        end,
      },
    },
    opts = {
      backend = "ueberzug",
      integrations = {
        markdown = {
          enabled = true,
          clear_in_insert_mode = false,
          download_remote_images = true,
          only_render_image_at_cursor = false,
          filetypes = { "markdown", "vimwiki" }, -- markdown extensions (ie. quarto) can go here
        },
        neorg = {
          enabled = true,
          clear_in_insert_mode = false,
          download_remote_images = true,
          only_render_image_at_cursor = false,
          filetypes = { "norg" },
        },
      },
      max_width = nil,
      max_height = nil,
      max_width_window_percentage = nil,
      max_height_window_percentage = 50,
      kitty_method = "normal",
    },
  },
})

package.path = package.path .. ";" .. vim.fn.expand("$HOME") .. "/.luarocks/share/lua/5.1/?/init.lua;"
package.path = package.path .. ";" .. vim.fn.expand("$HOME") .. "/.luarocks/share/lua/5.1/?.lua;"

vim.opt.number = true
vim.opt.conceallevel = 2
vim.opt.winbar = "image.nvim demo"
vim.opt.signcolumn = "yes:2"

local content = [[
# Hello World

![This is a remote image](https://gist.ro/s/remote.png)
]]

vim.schedule(function()
  local buf = vim.api.nvim_create_buf(false, true)
  vim.api.nvim_buf_set_lines(buf, 0, -1, true, vim.split(content, "\n"))
  vim.api.nvim_buf_set_option(buf, "filetype", "markdown")
  vim.api.nvim_set_current_buf(buf)
  vim.cmd("split")
end)

And this is what the minimal example looks like:

Am I missing something?

3rd / image.nvim
