Error when switch buffer

[ray-x]

When buffer switch got following error: It may be caused by hydra floating windows not exited properly. The hydra timer is still running but the hydra floating window is destroyed.

E5555: API call: Buffer is not 'modifiable'

Can't reproduce. Need more info.

[ray-x]

If hydra exits correctly with keymaps, there will not be any errors. One way to reproduce

1. create a hydra floatwindows
2. use mouse to click the floating window
3. enter some command in command line ( I have plugins e.g. wilder and cmp autocomplete enabled when entering command mode and will create a floating window)
4. see errors.

[anuvyklack]

Still can't reproduce. I don't use wilder, but with cmp the command line and buffer completion float windows work fine together with hydra hint window.

[anuvyklack]

Can you make a video? Or share a minimal config to reproduce.

I think might be wilder.nvim

[anuvyklack]

This is very strange. You wouldn't be able to select hint window. I use vim.api.nvim_open_win with focusable = false

@ray-x I remember that there is a bug in bufdir.nvim due to read-only buffer: https://github.com/elihunter173/dirbuf.nvim/issues/45

Does restoring your neovim version before https://github.com/neovim/neovim/commit/0cf5cd1ac9c8ec31c1d2f1b1a6585153a45fc4e9 fix the issue for you? Not sure though about the exact semantics of what neovim considers as "nofile".

Otherwise, you need to provide a minimal config.

I updated to neovim latest and it still occurs. I am not using dirbuf.nvim But I using wilder.nvim which may related to this. And the error is from here:

  if a:state.api.need_timer()
    let l:render_id = a:state.render_id
    call timer_start(0, {-> s:render_lines_from_timer(l:render_id, a:state, a:ctx, a:result)})  <-- here
  else
    call s:render_lines(a:state, a:ctx, a:result)

Not quite sure if this is related: https://github.com/gelguy/wilder.nvim/issues/140
