Description

• create a rust project cargo new cmptest cd cmptest cargo build nvim . type assert and press Ctrl-Space to open the completion window if the terminal size is less than certain amount the main completion window and details windows overlap each other and the main completion window is not readable if you resize the terminal then it fixes

Steps to reproduce

• create a rust project cargo new cmptest cd cmptest cargo build nvim . type assert and press Ctrl-Space to open the completion window if the terminal size is less than certain amount the main completion window and details windows overlap each other and the main completion window is not readable

Expected behavior

Expected : windows resize according to terminal size instead of overlapping

Actual behavior

completion windows overlap and cannot be read

Additional context

I used both neovim with my own config and also lunarvim (community config) they both behave the same way for certain rust types. this is reported by many users. my neovim nvim-cmp config https://github.com/salimp2009/deskmach_config/blob/main/nvim/.config/nvim/lua/user/plugins/nvim-cmp.lua

I have the same problem

me too

I researched and this issue seems to show how to fix it https://github.com/hrsh7th/nvim-cmp/issues/1154

I researched and this issue seems to show how to fix it #1154

yeah but I dont think that issue is even closed . and not sure if you really want to remove the menu because it shows where the completion is coming from . I currently have this

    vim_item.menu = ({
        nvim_lsp = "[LSP]",
        nvim_lua = "[NVLUA]",
        luasnip = "[SNPT]",
        buffer = "[BFR]",
        path = "[PATH]",
        cmp_tabnine = "[TBNI]",
        codeium = "[CDEM]",
        copilot = "[CPLT]",
        crates = "[CRAT]",
        emoji = "[EMOJ]",
    })[entry.source.name]

Removing all those looks like a just temporary workaround
