Some keys are repeated in neovim 0.12.0

[niveK77pur]

Issue Description

Inside of neovim 0.12.0, I notice some characters get triggered twice. So far, I have noticed when I want to insert ! it inserts !! as if I typed it twice (the second character appears with a very slight delay, quite literally as if I would hit the key twice to insert it twice). Same goes for ]. I observe this in all of neovim, no matter which mode I am in.

There is a related issue with alacritty and neovim as well: neovim/neovim#31806

I confirm that this does not happen with neovim inside of Konsole. Nor do the ! and ] get triggered twice outside of neovim.

Expected Behavior

Every key should only be triggered once inside of neovim (just how I type it on the keyboard).

I.e. when in normal mode and typing :!ls on the keyboard should produce exactly :!ls in the command line

Actual Behavior

typing :!ls on the keyboard produces :!!ls.

If I am fast enough to hit the following key, the second ! does not appear, but this is hardly the desired behaviour.

Reproduction Steps

1. Open ghostty
2. Open neovim nvim --clean
3. Type :! (note it will insert :!!, with the second ! appearing with a slight delay)
4. Alternatively, type /] (note how it will insert /]] with a slight delay as well)

Minimal Ghostty Configuration

_Empty config_

Additional Relevant Configuration

This is reproducible with stock configurations for both ghostty and neovim!

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 had the same issue on Arch Linux + Hyprland + Neovim 0.12.1 with a Swiss German (ch/de) keyboard layout.
Both ! and ] (both on the bracket_right physical key) were doubled. But only in Neovim. The Nano text editor for example had no problems.

The Ghostty terminal inspector confirmed two consecutive press bracket_right events for a single keypress.
Tested the same setup in Kitty — no issue there.

Workaround: Reverting to Ghostty 1.2.3 fixes it for the latest Neovim 0.12.1 version. The bug appears in all 1.3.x versions.

Same here, with the Swiss German Layout as well. 👍
(NixOS, Niri, Neovim v0.12.1, Ghostty 1.3.1)

Thanks for the workaround tip!

[niveK77pur]

I confirm I am using a swiss french layout, thanks for the workaround!

[boredcoder411]

this workaround doesn't work for me (using the swiss french layout)
oddly enough this also happens in alacritty, I think this is an issue in neovim

[74k1]

@boredcoder411 what version of alacritty and neovim are you using? I'll see if I can repro this issue there as well.

I'm using spanish layout, so the repeated keys for me are {} and [], but I've noticed there's a way to not make them repeat. It's very uncomfortable, I'm not saying it's a solution, it might help identify the issue though
