System them in macos with ghostty doesn't apply opacity

Description

First of all thank you for the effort making opencode great. One regression I still see after system theme was shipped for the version 1.* is that it doesn't pick up the opacity at least in Ghostty.

OpenCode version

1.0.39

Steps to reproduce

Open a ghostty terminal with config:

background-opacity = 0.9
background-blur-radius = 10

Enter to opencode
Select system theme

Operating System

mac os 26.0.1

Terminal

Ghostty

This issue might be a duplicate of existing issues. Please check:

Updating system theme requires hard reboot to fix #1587: Both involve system theme not updating/applying properly and may require restart to work correctly

Feel free to ignore if none of these address your specific case.

same issue with alacritty on Linux no background transparency, old system theme prior to 1.0 did not have this issue

Same issue on ghostty on mac.

@joshmedeski

how can i enable it after this issue fixed ? like @joshmedeski does on wezterm , I haven't seen setting in previous issues or pull requests.

The system theme was dropped when the opentui version was released, hopefully we can add it back soon.

Its already added now. Only the opacity is missing.

w fix, I saw this after fighting with opencode for a hot second. I'm on 1.0.46 and I've set my default theme to be that of my system.

{
  "$schema": "https://opencode.ai/config.json",
  "theme": "system"
}

Apparently this is all you have to do and it should respect the transparency values you've set in ~/.config/ghostty/config

wait so does it work?

no work in 1.0.58, wezterm

On ghostty 1.0.58 and it won't even respect my system theme on ghostty

Iv been lurking on this ticket for awhile since I really want this change. I took a look at it and at least for the background its pretty easy to alter the generateSystem function to default bg to transparent while that leaves all other settings the same. But that is not a valid solution for the long term.

We cannot by default set a transparent background for the system.
OpenTui cannot reliably detect if a terminal is running a transparent or blurred setting. So we get no values back there to help at runtime for the system styling.
We cannot bundle a transparent theme as there are required options that would make it no longer system styled.

If all of those are true, you need a new settings file field for theme overrides that would smoothly allow for small tweaks like this to any system or bundled theme. And to me that is a clean approach to this which I believe Zed ide does as well.

I hope that at least we can spark more conversation here in this ticket and come to a decision on the right direction for a solution to this problem.

@KeentGG that's the mac os Tahoe tabs :)

oh thanks, i forgot i had it also but im using tmux instead of native tabs

Following as I'm also seeing this issue using Ghostty 1.2.3 on Tahoe 26.0 despite trying the system theme.

Not working with Warp terminal in Macos, I am using opencode v 1.1.15 and Warp v0.2026.01.07.08.13.stable_01

fix(tui): respect terminal transparency in system theme

@rekram1-node When you get time can you review my thoughts here so we can confirm whether or not we need a more detailed design and review to be in place to enhance theming as a whole in Opencode?

Same issue on ghostty on mac.

same
ghostty
macos

Same situation for iTerm2.app of macOS.

For anyone who might benefit from it, the lucent-orng has transparent set as background color.

Not a fix, but does the trick for me.

Screen.Recording.2026-01-30.at.21.11.01.mov

I'm on 1.1.46, macOS Tahoe 26.2 and Ghostty 1.2.3

Why lucent-orng works but system doesn't:

lucent-orng sets background: transparent AND defines selectedListItemText with solid contrasting colors. The system theme can't do this—PR #4408 tried adding transparency but broke text contrast on selected items (#4369), so it was reverted.

Workarounds:

Use lucent-orng theme
Create a custom theme: copy lucent-orng.json to ~/.config/opencode/themes/, modify colors while keeping background: transparent and selectedListItemText defined

A proper fix needs a theme override system or a system-transparent variant.

A system-transparent variant would be nice. I just want the existing system theme with the old transparent background I had before opentui

I didn't mention it here cause the PR is linked automatically but I've fixed this on #8467 (at least it did work for me locally using Ghostty)
