Kitty background color changed?

[xfzv]

My Kitty color background is #1e1e20. I've just noticed that when triggering kitty-scrollback with either kitty_mod+h or kitty_mod+g, it changes to #1c1d23.

I'm pretty sure it was sticking to the Kitty background color until recently, but maybe I'm wrong.

I tried to downgrade to older versions (as far as v2.0.0), same behavior. Also occurs without loading my Kitty theme config file:

Maybe it's forced somehow and it's completely normal?

My config:

• kitty-scrollback.lua

return {
  "mikesmithgh/kitty-scrollback.nvim",
  cmd = { "KittyScrollbackGenerateKittens", "KittyScrollbackCheckHealth" },
  event = "User KittyScrollbackLaunch",
  opts = {},
}

• kitty-scrollback-config.lua

vim.opt.runtimepath:append(vim.fn.stdpath("data") .. "/lazy/kitty-scrollback.nvim")

require("kitty-scrollback").setup({
  global = function()
    return {
      visual_selection_highlight_mode = "reverse", -- most likely not related because it only affects selection, but I tried without this, or with "darken", "kitty", "nvim" and got the same behavior
      status_window = {
        icons = {
          nvim = "",
        },
      },
    }
  end,
})

I've just tried in a virtual machine and the background color doesn't change.

Might be a Neovim change upstream, I'll investigate and report later.

Edit: Indeed, it looks like it's due to a recent Neovim change.

On the VM with Neovim 0.9.4, the background color doesn't change. I tried with 0.10 which I'm also running on my main system and got the same behavior.

There have been a few commits related to colors in the last few days, maybe related?

Hey @xfzv thanks for the detailed information! Yes, it is due to the new default neovim coloscheme. See neovim/neovim#26334 (comment)

I have a ticket to fix this #93

There are a couple ideas there you could play with.

You might also want to try :colorscheme vim that is the previous default theme.

Awesome screenshots and details 😸 👍

I checked issues before opening this discussion but I thought that #93 was something else.

Sorry! 🙇
