Junk characters inside the scroll bar

This only happens with a big list (either large doc or long list of completions). See screenshots below.

My config:

    local cmp = require('cmp')
    local luasnip = require('luasnip')

    local has_words_before = function()
        local line, col = unpack(vim.api.nvim_win_get_cursor(0))
        return col ~= 0 and vim.api.nvim_buf_get_lines(0, line - 1, line, true)[1]:sub(col, col):match('%s') == nil
    end

    cmp.setup {
        formatting = {
            format = function(entry, vim_item)

[hrsh7th]

Thank you. I think it relates to persistence.nvim. I've fixed it maybe .

[folliehiyuki]

Thanks @hrsh7th I just updated to the latest commit and the scroll bar looks normal now.
