Background Opacity Setting Affecting Neovim Background

[timoclsn]

I'm using Ghostty on macOS und i like my terminal to have some background opacity.

I am using this config:

background-opacity = 0.9
background-blur-radius = 20

I'm using Neovim with the tokyonight theme. I have set transparency to false for tokynight in Neovim.

But it seems like the Ghostty background opacity setting is also affecting the Neovim background. In all the other terminal emulators i have tested (Wezterm, Alacritty) this is not the case. Which i like!

Is there a way to get this behaviour in Ghostty? Solid BG in Neovim but general transparent terminal?

(If i wanted I always could make my Neovim background transparent and have the terminal setting take affect this way)

I would look to your nvim configs, by default for my neovim window was a solid background color while my ghostty config was set to 80% until I added these lines to my init.lua

vim.cmd([[
  augroup TransparentBackground
  autocmd!
  autocmd ColorScheme * highlight Normal ctermbg=none guibg=none
  autocmd ColorScheme * highlight NonText ctermbg=none guibg=none
  augroup END
]])

But what you described first ist exactly what I want:

• Ghostty Opacity 0.9
• Neovim solid background

I think this could be the "issue" as I have Ghostty and Neovim set to tokyonight.

I now have worked around it by overriding the terminal background with a sliiiightly other background color so that it doesn't match my editor theme.

theme = tokyonight
# Slightly changed background color so that neovim background doesn't get transparent
background = 1A1B25 

But would be nice to know if this is a bug or intended behaviour.

You can easily recreate the behavior using ghostty itself, specifically when ruinning ghostty +list-themes with a background-opacity < 1, it will show a transparent background when previewing your current theme, but be opaque when previewing any other theme.
