Bug: Flicker Issue on Lualine Still Exist

[ochi12]

Self Checks

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

Expected behaviour

This was Already Solved In issue #744 I already looked up the source code in and confirmed it was already commited d2a727.

Actual behavior

The flicker issue is still bugging me Specifically when toggling NeoTree. Also when opening Telescope just like in [ issue #1220 ] It also do flicker

Minimal config to reproduce the issue

local lualine_c = function()

    local devicons = require("nvim-web-devicons")
    local theme = require("lualine.themes.catppuccin")
    local mocha = require("catppuccin.palettes").get_palette("mocha")

    -- overriding default colors
    theme.normal.c.bg = "#242435"

    -- defining section colors
    local z_colors = {
        left = {
            bg = theme.insert.a.bg,
            fg = theme.insert.a.fg,
        },
        right = {
            bg = theme.normal.b.bg,
            fg = theme.insert.b.fg,
        },
    }

    local y_colors = {
        left = {
            bg = mocha.red,
            fg = mocha.base,
        },
    }

Also flickering for me. I tried 4 different themes, and they all had the issue, so it's not associated with a particular theme.

I'm using the latest iTerm app, on an M3 Max MacBook Pro.

I'm running into the same issue when toggling Netrw. Lualine also flickers when I open new buffers from within Netrw. These flickerings do not happen every time; more like every 3-4 time.
