Ignore the warnings about snack. I added the input and picker opts.

Describe the bug

The TUI is broken when toggling opencode.

Kitty.mp4

return {
  "nickjvandyke/opencode.nvim",
  version = "*", -- latest stable release
  dependencies = {
    {
      "folke/snacks.nvim",
      opts = {
        input = { enabled = true },
        picker = { enabled = true },
      },
    },
  },
  keys = {
    {
      "<leader>as",
      function()
        require("opencode").ask("@this: ", { submit = true })
      end,
      desc = "Ask opencode",
      mode = { "n", "x" },
    },
    {
      "<leader>at",
      function()
        require("opencode").toggle()
      end,
      desc = "Toggle opencode",
      mode = { "n", "t" },
    },
  },
}

Idk why this could be happening.
Very weird.

NVIM v0.11.4
Build type: Release
LuaJIT 2.1.1760617492
Run "nvim -V1 -v" for more info

Kitty Terminal
Version 0.45.0 (0.45.0)

Steps To Reproduce

1. Init with minimal config
2. Just toggle opencode

Expected Behavior

TUI shouldn't break.

I'm not sure exactly where the issue lies, but it happens with snacks.terminal too #166

I have seen other strange rendering behavior in opencode's TUI. I already have one workaround to fix it rendering with an empty column on first render. So I'm inclined to think it's on their end? Although if someone finds a workaround for this, happy to merge it!

For me it only happens when I have two vertically-split buffers already. Strange that it happens with just one for you.

I have the same issue

[Barmanji]

Any solution you have found? @orderbynull @nickjvandyke

[nickjvandyke]

I haven't had time to investigate further unfortunately. But I encourage someone to poke around for a fix!

It seems to work fine when I use snacks.terminal, but the same issue occurs when using the default configuration or launching via toggleterm.nvim. My terminal emulator is Ghostty.

[nickjvandyke]

This seems suddenly fixed for me in opencode v1.3.0. Lmk if that's not the case for you!

not working for me.

[nickjvandyke]

Maybe try upgrading your terminal app too - ghostty recently released 1.3.1 which may be relevant for me.
