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

   • OpenCode encounters automatically growing unreadable characters #16507: Similar issue with automatically growing unreadable/garbled characters in the TUI (SGR mouse mode sequences leaking)
   • Random Artifactts In Terminal After Running #5936: Random artifacts appearing in terminal, also on Windows, tied to mouse movement after exiting opencode

   If your issue is the same, please consider adding your context there instead.

   I’m seeing similar behavior in Ghostty on macOS using the fish shell. The random characters/artifacts appear when I scroll or when something is printed to the terminal (for example, when OpenCode initializes). No plugins enabled.

   Environment:

   • macOS 26.3
   • Ghostty 1.2.3 stable
   • Shell: fish 4.4.0
   • Node: v24.13.0
   • OpenCode: 1.2.20

   Let me know if there are any specific logs or checks that would help.
