ふむ。これもpathの影響がありそうです。@tyruさんも前 vimproc の呼び出しに失敗すると言っていましたが、それはこれかもしれません。
@tyruさんの環境もWindows8で日本語がユーザー名になっていましたか？
だとすると、この問題とは違いますね
Please read other issues. Your issue is already duplicated. https://github.com/nvim-lua/completion-nvim/issues/403 https://github.com/nvim-lua/completion-nvim/issues/399
The important thing is completion-nvim is broken currently. It is not maintained well. I recommend for you to use other auto completion plugins instead.
Yes. You are right. And the fix is already exists. https://github.com/nvim-lua/completion-nvim/pull/400 But it is not merged yet... I don't know why.
It seems neovim's LSP implementation problem. You can create the issue.
@tami5 Your reproduce steps are very fuzzy.
I have tested coc.nvim and if I use backspace, completion popup flicker.
