Bug: constant background cpu usage

[ces42]

Self Checks

• I'm using the latest lualine.
• I didn't find the issue in existing issues or PRs.

Expected behaviour

Nvim cpu usage should be near zero, especially when not using the editor.

Actual behaviour

when lualine is loaded, nvim cpu usage is always 1-2% (on an intel Ultra 9 185H). The issue still persists if I strip all component from lualine (see config file).

Minimal config to reproduce the issue

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


require("lazy").setup({
    spec = { 'nvim-lualine/lualine.nvim',
        -- ~/.config/nvim/lua/lualine_config.lua
        -- event = 'UIEnter',
        config = function()
            require'lualine'.setup{
                sections = {
                    lualine_a = {},
                    lualine_b = {},
                    lualine_c = {},
                    lualine_x = {},
                    lualine_y = {},
                    lualine_z = {},
                }
            }
        end,
    }
}
)
