BUG: Black/White background color on hover windows since neovim v0.10

Neovim Version (nvim -v)

0.10.0-2

Operating System / Version

ArchLinux 6.8.9-arch1-2

Describe the Bug

All hover windows (rename, move, etc) have a pure black/white background, based on the colorscheme's style(dark/light). This started to occur with the update to neovim 0.10. I also tested several color schemes, including neovim's default scheme and it appears on all of them.

I experience the same behavior for hover windows of lspsaga and lazy's hover window. skim hover windows however seem to work just fine.

Things I tried

• Checked different terminals (xterm and alacritty) , but it appears on both terminals.
• Unset all environment variables from my environment (except $HOME). Didn't do anything. As soon as settermguicolors is activated, the behavior appears.
• Minimal reproducable setup, which can be seen below.
• Switch back to v0.9, whichfixes the problem. The behavior only occurs on v0.10.

Workaround

Setting set :notermguicolors fixes the problem! It just looks bad.

Similar issues

I stumbled upon this neovim issue, but it seems to be a different problem, even though it sound suspiciously similar. Their minimal config works perfectly fine on my system and the transparent windows is displayed correctly.

Steps to Reproduce

1. Run neovim with nimimal reproducable config.
2. Press m on neo-tree to open move menu.

Expected Behavior

The background shouldn't switch to black/white.

Your Configuration

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
    vim.fn.system({
        "git",
        "clone",
        "--filter=blob:none",
        "https://github.com/folke/lazy.nvim.git",
        "--branch=stable", -- latest stable release
        lazypath,
    })
end
vim.opt.rtp:prepend(lazypath)

require("lazy").setup({
    ----- Libraries -----
    "MunifTanjim/nui.nvim",
    "nvim-lua/plenary.nvim",
    "nvim-neo-tree/neo-tree.nvim",
})

vim.cmd(":Neotree source=filesystem")

I played around a bit more and found out that the issue doesn't happen on the habamax colorscheme doesn't appear to have this issue. The original vim colorscheme also seems to look fine (even though the colors are extreme).

habamax:

vim:

What's confusing though is that the default neovim colorscheme has this problem as well as the other three colorschemes I tested. So I assume this is an issue introduced with the new colorscheme?

default:

I am also experiencing a similar issue. I observe the black background on the status lines of inactive windows and inside the Lazy UI. I'm not certain if it was the cause but I started noticing the behavior after installing lualine and setting cmdheight=0 but reverting these actions didn't fix it.

[Nukesor]

Same thing here. The Lazy UI is affected as well, including the top bar.

What's interesting is that the Lazy UI uses and sets the habamax colorscheme by default every time it starts up. This seems to break something for the top line, which otherwise works perfectly fine for me.

[miversen33]

Just popping in here to confirm that I can recreate your issue with the provided config.

What's interesting is if you add literally any valid value for popup_border_style, it corrects the issue

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not (vim.uv or vim.loop).fs_stat(lazypath) then
    vim.fn.system({
        "git",
        "clone",
        "--filter=blob:none",
        "https://github.com/folke/lazy.nvim.git",
        "--branch=stable", -- latest stable release
        lazypath,
    })
end
vim.opt.rtp:prepend(lazypath)

require("lazy").setup({
    {
        "nvim-neo-tree/neo-tree.nvim",
        dependencies = {
            "nvim-lua/plenary.nvim",
            "MunifTanjim/nui.nvim",
        },
        branch = "main",
        config = {
            popup_border_style = "single",
        }
    },
})

vim.cmd(":Neotree source=filesystem")

Valid values for popup_border_style can be found in :h api-win-config under the config.border section

border:       Style of (optional) window border. This can either
                    be a string or an array. The string values are
                    • "none": No border (default).
                    • "single": A single line box.
                    • "double": A double line box.
                    • "rounded": Like "single", but with rounded corners
                      ("╭" etc.).
                    • "solid": Adds padding by a single whitespace cell.
                    • "shadow": A drop shadow effect by blending with the
                      background.
                    • If it is an array, it should have a length of eight or
                      any divisor of eight. The array will specify the eight
                      chars building up the border in a clockwise fashion
                      starting with the top-left corner. As an example, the
                      double box style could be specified as: 
                      [ "╔", "═" ,"╗", "║", "╝", "═", "╚", "║" ].

                      If the number of chars are less than eight, they will be
                      repeated. Thus an ASCII border could be specified as 
                      [ "/", "-", \"\\\\\", "|" ],

                      or all chars the same as 
                      [ "x" ].

                    An empty string can be used to turn off a specific border,
                    for instance, 
                     [ "", "", "", ">", "", "", "", "<" ]

                    will only make vertical borders but not horizontal ones.
                    By default, `FloatBorder` highlight is used, which links
                    to `WinSeparator` when not defined. It could also be
                    specified by character: 
                     [ ["+", "MyCorner"], ["x", "MyBorder"] ].

Not really sure what is going on but this workaround seems to work for me.

Without setting popup_border_style

With setting popup_border_style to something (single) in my case

IIRC Neo-tree uses nui for the popup handling, might be a nui regression?

[rishyramen]

Sorry, I realized my issue was unrelated (I don't use neo-tree). If it helps the behavior I observed was due to enabling transparent floating windows with my theme (kanagawa-dragon) but I accidentally copied over an override for the LazyNormal highlight group which caused the Lazy floating window to have a black background.
