Hi, I can confirm that I see this bug on NixOS in Kitty terminal windows with Neovim as the text editor. I can also confirm that this happens with the most recently release mentioned in the issue but does not occur with prior versions. I happened to switch to OpenCode 1.0.64 and did not notice any lag in the Neovim text editor, although it is very noticeable in OpenCode 1.0.85. Thanks for all of your work on OpenCode, it is really awesome!

might be a duplicate of existing issue #4209

If fixing it in opentui makes sense, then great, but I did create #4595 in case it just makes the most sense to escape raw input mode during the editor session.

I think I will close in favor of #4209 I think they are heavily related
