hi, are there any updates to this? If not, I can try to fix it. But I'd some guidance on where to start looking

Are you still seeing these issues in latest 1.1.51?
disrupted commentedon Feb 4, 2026
yes
R44VC0RP commentedon Feb 4, 2026
I am not able to repro this, can you share more about your setup?
disrupted commentedon Feb 4, 2026
this is without any custom opencode.json

now it's back on 1.1.53 🎉
ishaksebsib commentedon Feb 6, 2026
what about you @notAunty?
fozcodes commentedon Feb 7, 2026
I'm on 1.1.53 and it's still not working. Not via opencode.jsonc or via the UI:

@R44VC0RP I think I figured it out. I'm using Tmux in Ghostty with these configs:
When I use Opencode outside of Tmux in just Ghostty, I have the
systemoption in/themeand it loads automatically from my~/.config/opencode/opencode.jsonc.When I jump back into Tmux, the option's gone and it falls back to the default Opencode theme.
I guess this is all to say, I think it has to do with terminal color settings. These were working with
< 1.0for me (hadn't updated in a while until end of last week).notAunty commentedon Feb 15, 2026
@fozcodes let me try it out. I'm on tmux on Kitty.terminal
v1.2.4
notAunty commentedon Feb 16, 2026
Managed to get back my
systemcolor by following this article.Feels like
opencodecould do better at conveying to the user that the system theme is hidden due to issues with terminaltruecolorsupport, rather than hiding the option, especially when it doesn't have light/dark theme auto-switching.Consider this issue closed for me, thanks @fozcodes for the idea.
fozcodes commentedon Feb 19, 2026
Yeah, I can't do that. I have these settings so that Victor Mono works correctly in my Tmux env. I'm also on Ghostty 1.2.3.
Glad you got it working though!
(Also, I upgraded to the latest release and
systemis still not available)akronb commentedon Feb 19, 2026
@fozcodes This might be related to fetching the system theme palette.
There’s a bug in
opentui(anomalyco/opentui#705) causing a 5s delay at startup when the system theme is active. Additionally, if a different theme is selected on start, I can't switch back to the system theme until the palette is successfully retrievedfozcodes commentedon Feb 20, 2026
@akronb thanks!
It was actually something else though; Tmux blocks Operating System Commands by default. I had to add this to my
.tmux.conf:I actually don't know too much about this TUI stuff, so I had the robot help me out. It tried a few things but eventually was able to narrow it down: https://opncd.ai/share/kIEsKk7r
