Hmm, I usually use nightly so I thought that was the difference but even when I downgrade to v0.9.1 I still cannot reproduce the issue.

Here are my screenshots.

• vim.opt.cmdheight = 0
  

• vim.opt.cmdheight = 1
  

• vim.opt.cmdheight = 2
  

The following code is what neo-tree is basically doing in the back. Could you execute this code in your environment?

Open neovim
Create a file named test.lua
Copy the following code
Run :so once

vim.keymap.set("n", "<Leader>r", "<Cmd>source<CR>", {})
vim.cmd("language en_US.utf8")

local opts = {
  prompt = "Question: foo bar" .. "\n",
  default = "~/",
}

vim.ui.input(opts, function(msg)
  vim.print(string.format([[msg: %s]], vim.inspect(msg)))
end)

• :lua vim.opt.cmdheight = 0
• <Leader>r
• See what happens
• :lua vim.opt.cmdheight = 1
• <Leader>r
• See what happens
• :lua vim.opt.cmdheight = 2
• <Leader>r
• See what happens

Ok, I was able to reproduce inside neo-tree but I'm now confused that the above code does work despite both should be doing the exact same thing.

I think I'll deal this with a workaround.

It works! @pysan3 Thank you very much!
