Description

Keybinds like the leader key Ctrl-X are not working on tmux. Besides that, when I move my mouse over the app it starts to display junk characters

OpenCode version

1.0.20

Steps to reproduce

  1. Open up a tmux session
  2. Open opencode
  3. Try to press ctrl-x or move the mouse

Screenshot and/or share link

For ctrl-x it just writes ^X. For the mouse I attached a screenshot.

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

  • #3199: Similar garbled/junk text display when mouse interactions occur, also causes input blocking
  • #3851: Leader key (ctrl-x) not working properly in v1.0 - same keybind issue you're experiencing
  • #1930: Cursor positioning problems in tmux environments with similar terminal setup (WSL + alacritty)

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