@XXiaoA what plugin is that? On the latest Neovim nightly (v0.8.0-dev-1029-g05893aea3), :lua vim.ui.input({}, function() end) doesn't open such popup. The input is in the command line bar, at the bottom:

Sorry, I forgot I installed dressing.nvim. But it used the standard highlight groups for neovim floating windows. See here.

OK thanks for double checking 👍

Maybe @sainnhe can confirm, but to me it seems like a conscious design decision for this theme:

Removing specific background styling makes the popup blend in, but as a result it also doesn't stand out from the main window:

The image (purple theme) you shared earlier does set the border background to the same color as the default background, but not in the center, so the result looks glitchy:

Adopting this style in Gruvbox Material looks equally glitchy in my opinion:

Out of these 3 variants, I personally find the current style the most readable while working with floating popups.

For the time being, my suggestion would be to apply local customisations using autocmd to tailor the look and feel of floating popups to your needs:

:page_facing_up: .vimrc (Vim)

```vim " Apply custom highlights on colorscheme change. " Must be declared before executing ':colorscheme'. augroup custom_highlights_gruvboxmaterial autocmd! " floating popups autocmd ColorScheme gruvbox-material \ hi NormalFloat guibg=#282828 | \ hi FloatBorder guibg=#282828 augroup END colorscheme gruvbox-material ```

:page_facing_up: init.lua (Neovim)

```lua -- Apply custom highlights on colorscheme change. -- Must be declared before executing ':colorscheme'. grpid = vim.api.nvim_create_augroup('custom_highlights_gruvboxmaterial', {}) vim.api.nvim_create_autocmd('ColorScheme', { group = grpid, pattern = 'gruvbox-material', command = -- floating popups 'hi NormalFloat guibg=#282828 |' .. 'hi FloatBorder guibg=#282828' }) vim.cmd'colorscheme gruvbox-material' ```

Okay, it does maybe a design for this colorscheme. I'll try use autocmd to configure it.

Hi, the autocmd works perfectly, thanks. I just want to report that for the autocompletion panel with borders, it has the same behavior. Also, in the Harpoon pop-up panel, if you go to visual mode, you can't see the text selection area; the colors are the same.
