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

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

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

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

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.

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 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 Had the same issue. Looks to be working for me now with nixpkgs 1.0.180 (https://github.com/NixOS/nixpkgs/issues/472229).
