Describe the bug

Quite often if I Ctrl-C to exit insert mode, some of the helpful auto-suggestions that appear in the pop up near the cursor (what's that thing called?) don't go away. They stay there even if I Ctrl-L or :redraw! The only way to get them to go away is to trigger another auto-suggestion (by pressing tab or a key that triggers auto-complete).

Reproduce the bug

The vanilla mini.vim was enough to reproduce the bug, but it took using the arrow keys to select a very long suggestion option, and then Ctrl-C'ing in order to reproduce it. But it did reproduce after a while. Screenshots below.

vim set nocompatible set runtimepath^=/path/to/coc.nvim filetype plugin indent on syntax on set hidden

• Start (neo)vim with command: vim -u mini.vim

• Operate vim.

Screenshots (optional)

With mini.vim:

Sometimes it seems like it's most often a problem with the extra pop up providing additional information on the side. This was taken before Ctrl-C:

And after:

Thanks for an awesome plugin! I use it all the time and it is a huge improvement to my workflow.

I've had this happen too, if you click on the suggestion and bring it into focus you can ':q' and it will close the suggestion but keep the other stuff open.

[jacobsandlund]

@kyle-mccarthy oh interesting, and is there a way to navigate to the suggestion without using the mouse?

[chemzqm]

Try :call popup_clear(), it could be failed to get closed because the async manner of coc.nvim.

[jacobsandlund]

Ah, that works for me. I also realized I could inoremap Ctrl-C to hit escape. Even with that mapping to escape it still leaves a small window on rare occasion. But this works for me now.

Try :call popup_clear(), it could be failed to get closed because the async manner of coc.nvim.

:call popup_clear() returns E117: Unknown function: popup_clear. This function has been removed?

And I find that :call coc#util#close_popup() can work.
