The default theme "dark" mode of the system has failed.

[cycle2zhou]

Description

configuration:

The system theme is dark, and the terminal is also dark. However, as soon as you open opencode, it automatically switches to a bright theme.

ghostty theme=GitHub Dark
The opencode 1.14.18 and previous versions are all functioning properly.
However, what's interesting is that this issue only occurred in Ghostty. The original terminal and iterm2 were both fine.

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

• no longer respects system theme (macos ghostty) #20926: Same issue — dark theme not respected in macOS + Ghostty
• Themes always render light variant on macOS regardless of terminal dark background (OSC 11 detection broken) #23196: Same symptom — light variant always renders on macOS regardless of terminal dark background (also Ghostty)

Please review those issues and add a comment there if your situation matches, rather than filing a new report. If your issue is distinct, feel free to clarify the differences.

I'm also experiencing this. Also, changing the theme inside opencode doesn't seem to be preserved as of 1.14.19, it snaps back to system on next restart (which is incorrectly light mode, Ghostty with dark theme) - in 1.14.18 there was no such issue.

I am experiencing this too. My system is dark but opencode cli keeps using light mode on any theme.

Same happens with me now after upgrading

Just updated and got flash banged. I also use system default dark mode and ghostty on osx

opencode --version
1.14.19

Just found this on 𝕏 https://x.com/thdxr/status/2045175662130946205?s=20

ctrl+p - Switch to dark mode - seems to at least get it back in to dark mode

at least gets it back to dark mode.
