Issue Description

When I select and copy a piece of text in opencode, it copies that text correctly. However, when I try to copy text from an external source and paste it into ghostty with opencode open, it fails to paste the new text and instead pastes the previously copied value.

This issue occurs only in ghostty (affecting all instances of ghostty even those which does not run opencode) and only with the https://github.com/sst/opencode command-line tool.

I tried reproducing the issue in GNOME Terminal, and it works as expected with no problems.

Workaround: Restarting all instances of ghostty resolves the issue temporarily.

Notes:

Issue happens with and without tmux
Issue happens on default ghostty config and on my own.
All other CLI tools like neovim and others work as expected even gemini-cli if comparing to current problem.

Expected Behavior

When selecting and copying text in opencode, it copies the selected text correctly. When copying text from an external source and pasting it into ghostty (using Ctrl+Shift+V), it pastes the newly copied text instead of the previously copied text from opencode.

Actual Behavior

When selecting and copying text in opencode, it copies the selected text correctly. However, when copying text from an external source outside ghostty and attempting to paste it (using Ctrl+Shift+V) into any ghostty window, it incorrectly pastes the previously copied text from opencode instead of the newly copied external text. This issue affects all instances of ghostty.

Reproduction Steps

Open one or more instances of ghostty.
In one ghostty instance, run the opencode command-line tool (i used version v0.4.2).
Select and copy a piece of text within opencode (e.g., using mouse selection or keyboard shortcuts).
Copy different text from an external source outside ghostty (e.g., from a web browser or another application).
Attempt to paste the external text into any ghostty instance (using Ctrl+Shift+V).
Observe that the pasted text is the previously copied text from opencode instead of the newly copied external text.
Verify that this issue occurs across all open ghostty instances.

I acknowledge that:

I have reviewed the FAQ and confirm that my issue is NOT among them.
I have searched the Ghostty repository (both open and closed Discussions and Issues) and confirm this is not a duplicate of an existing issue or discussion.
I have checked the "Preview" tab on all text fields to ensure that everything looks right, and have wrapped all configuration and code in code blocks with a group of three backticks (```) on separate lines.

I tried really hard to run opencode but they have bad documentation and I can only run a local model (I wont sign up for any / pay money)
in which with both lm-studio and ollama I just get errors trying to use it

hey @rhodes-b, thanks for looking into this issue!
imo they really have pretty good documentation https://opencode.ai/docs/
as an option if you don't want to subscribe on any service (pay money) u can try to use free tier from https://groq.com/ or https://openrouter.ai/ it should be enough to make few simple queries for tests to get some text appeared in your terminal

@mitchellh Hello! This problem is actually presented for me in 1.4.

To reproduce:

Arch Linux
KDE WM
Ghostty 1.4
Opencode 2.2.6

Copying in opencode, then pasting in another ghostty window fails. Then, after trying pasting, for example, in browser, I am again able to paste text in opencode. Happens only for Linux Ghostty (GTK), with no problem on MacOS. Issue was present in 1.3

Please open a new discussion instead of reviving a year-old one. Ghostty has changed significantly since then.
