i have to reopen telescope to see the changes ( changed hl groups )

Minimal config

vim.cmd [[set runtimepath=$VIMRUNTIME]]
vim.cmd [[set packpath=/tmp/nvim/site]]
local package_root = '/tmp/nvim/site/pack'
local install_path = package_root .. '/packer/start/packer.nvim'
local function load_plugins()
  require('packer').startup {
    {
      'wbthomason/packer.nvim',
      {
        'nvim-telescope/telescope.nvim',
        requires = {
          'nvim-lua/plenary.nvim',
          { 'nvim-telescope/telescope-fzf-native.nvim', run = 'make' },
        },
      },
      -- ADD PLUGINS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
    },
    config = {
      package_root = package_root,
      compile_path = install_path .. '/plugin/packer_compiled.lua',
      display = { non_interactive = true },
    },
  }
end
_G.load_config = function()
  require('telescope').setup()
  require('telescope').load_extension('fzf')
  -- ADD INIT.LUA SETTINGS THAT ARE _NECESSARY_ FOR REPRODUCING THE ISSUE
end
if vim.fn.isdirectory(install_path) == 0 then
  print("Installing Telescope and dependencies.")
  vim.fn.system { 'git', 'clone', '--depth=1', 'https://github.com/wbthomason/packer.nvim', install_path }
end
load_plugins()
require('packer').sync()
vim.cmd [[autocmd User PackerComplete ++once echo "Ready!" | lua load_config()]]

@fdschmidt93 any idea? :thinking:

I'll look into it in the next couple of days. I'll probably bisect neovim and figure out what actually changed upstream between 0.7.2 -> 0.8.0. Maybe its an upstream bug because i can't think of anything we should do differently.

Please be patient i have a pretty busy week but i'll try to find the time in the evening to do this :)

[siduck]

No worries! Take your own time :D

might be caused by https://github.com/neovim/neovim/pull/13457

I have not tested this, so i dont wanna point fingers to "bugs" or stuff, but it might be interesting to look into what actually changed in this PR and what we need to adept to fix this issue
