Can you try running the debug version like
OC_NO_KITTY_KEYBOARD=1 bunx opencode-ai@snapshot-kmdr-debug? Or try it in a terminal that does not support kitty keyboard, like Alacritty. I need to know if it is an issue with kitty keyboard input.darkmanno6 commentedon Jan 12, 2026
it works on Alacritty.
and I've noticed that different themes also affect this issue. For example, the
systemtheme exhibits this problem, while some others likeayudo not.Additionally, there seem to be some issues with the theme colors. I remember that the Materia theme is a dark theme, but now it's appearing as a light theme.

Could you try
bunx opencode-ai@snapshot-kmdr-debugagain if that input issue still happens in the terminal it happened before?darkmanno6 commentedon Jan 13, 2026
yes ,it still happened
kommander commentedon Jan 13, 2026
Weird. Did you try without any plugins, like without OMO?
darkmanno6 commentedon Jan 13, 2026

I want to get to the bottom of this. Can you get the opentui examples app from https://github.com/anomalyco/opentui/releases/download/v0.1.72/opentui-examples-v0.1.72-windows-x64.zip and run the "Keypress Debug Tool", type a few characters that cause problems in the prompt textarea, then trigger shift+s (sorry, western keybinding at the moment), which should create a json log file in the CWD with some info. Please share that.
darkmanno6 commentedon Jan 13, 2026
sorry，the app you provided is an .exe program, which I cannot use on my Mac system
kommander commentedon Jan 13, 2026
Sorry, so many windows issues, I mixed that up: https://github.com/anomalyco/opentui/releases/tag/v0.1.72 - there are releases of the example app for all platforms.

fix(pty): Add UTF-8 encoding defaults for Windows PTY

只要文件中含有 .git 文件就会出现这个问题，只要文件中不含有 git 目录就不会出现这个问题，或者使用 opencode 进入内部含有 git 目录的文件就不会出现这个问题
syllr commentedon Mar 3, 2026
@code-lixm 对,是这个原因,我把.git目录删了就不会出现这个问题了

Did this improve in the latest version?
