I cannot reproduce this. I've tried on v0.7.2 and on nightly. I've tried with my normal config and with a minimal config that consists of only

vim.o.list = true
require('aerial').setup({})

Could this be caused by some interaction with another plugin you're running? Can you try with a minimal config and see if the issue reproduces?

I'll make a minimal configuration ASAP. Unluckily it maybe in next weekend. because I'm gonna go to school tomorrow.
BTW, thx for ur awesome plugin! 😁

I see this too.

If you open Aerial, change focus and go back to the aerial split, then the visual bug disappears

[stevearc]

Still can't get it to repro, but I've switched to using the list option instead of listchars (which is the more correct way to do what I want anyway). Can you check it again and see if that made a difference?

@stevearc The minimal configuration I tried:

local o = vim.opt
o.runtimepath:append("~/repos/aerial.nvim/")
o.runtimepath:append("~/repos/indent-blankline.nvim/")
o.runtimepath:append("~/repos/nvim-treesitter")

o.list = true
o.listchars:append("space:⋅")

require('aerial').setup({})
require("indent_blankline").setup({})

for index, value in ipairs({}) do
    if index == value then
        print(index)
    end
end

This seems that there is conflict between aerial and indent-blankline

Thanks for the repro! I was able to narrow down the cause. Something aerial is doing does trigger it, but it's an autocmd + some behavior in indent-blankline that's causing the display issue. I've filed lukas-reineke/indent-blankline.nvim#482 to follow up.

Fixed upstream in version 3 of indent-blankline
