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

Syntax highlighting breaks for non-English text with file links, selection also behaves incorrectly #1857: Similar syntax highlighting problems, specifically mentions highlighting breaks and inconsistencies
Custom theme causes panic due to missing markdown properties #488: Custom theme issues with markdown properties causing rendering problems

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

Yeah we are gonna fix this soon and fix it before it's shipped

do you guys have a list ? might be better to know what you planned to avoid creating more issues. because I do see other things missing

im tracking open issues with opentui label, we also have some in our internal channels but im I think a decent # of them are issues on github too

Anything you see that you think needs to be addressed, issues are more than welcome! Worst case there is a duplicate but that's no biggie

For me it's also not highlighting code diffs.

I can reproduce this on Windows 11 using WezTerm with v1.0.107.

When I run from source with: bun install && bun dev, markdown text renders correctly. The rendering bug only appears when using the deployed binaries, whether downloaded directly or via a package manager.

Yeah we have been looking into it, something with bun single file executables makes the issue start happening, only affects windows

This issue is also occurring on v1.0.105 for me in ghostty/on NixOS

I'm seeing no code highlighting or diff highlighting after upgrading to 1.0.105 (don't recall seeing this issue with .20 or .78).

Markdown just looks like text.

I'm on NixOS/Linux, using kitty.

@bartman

@bartman @apekros both of you say 1.0.105 broke it, what about 1.0.104?

bunx opencode-ai@1.0.105

bunx opencode-ai@1.0.105

1.0.104 also doesn't work for me. I never saw markdown syntax highlight on 1.0.x

well i think ur on windows, right?, we are working on a fix for that

Confirmed it's on the Home Manager binaries for 1.0.105 on MacOS, too. Granted that's technically Nix binaries, but that means it's evidently an issue with the binary itself.

1.0.104 also doesn't work for me. I never saw markdown syntax highlight on 1.0.x

With bunx, both opencode-ai@1.0.105 and opencode-ai@1.0.104 the markdown syntax highlighting works.

I am unsure what has changed, on 1.0.45 on NixOS it works, but any later binary does not

I am unsure what has changed, but now on the nix binary I am not having issues since using bunx

Weird, the bunx executable is fine, but the Nix binaries are still messed up. (bunx on the left, Nix on the right)

I believe this is fixed on latest

@rekram1-node

@rekram1-node Thank you for the fix! I just upgraded to 1.0.132 and can confirm it's fixed on my Windows machine.

I can't test it because of the proxy issue. ;)

Still seems to be broken on the nixpkgs 1.0.133? Might be some weird dependency missing.

@ApprenticeofEnder

@ApprenticeofEnder Had the same issue. Looks to be working for me now with nixpkgs 1.0.180 (NixOS/nixpkgs#472229).
