[Windows] [Wezterm] Delay for `Esc` action

[driuba]

Describe the bug

After v0.65.0 update there is a second or so delay between pressing escape key and exiting from whatever section was opened. If escape is pressed multiple times within this delay window, the action is ignored completely. This does not happen on previous versions (v0.64.1 tested during reporting).

To Reproduce

Steps to reproduce the behavior:

1. Go to Local branches or Commits;
2. Press enter on a branch or commit;
3. Try to exit the view by pressing Esc;
4. There's a delay before action happening;
   a. Pressing Esc multiple times doesn't exit the view a all.

Expected behavior

There should be no delay, besides reasonable input handling one. Pressing Esc multiple times should exit nested views.

Additional context

The problem seems only specific to Wezterm and v0.65.0 version combination. It doesn't happen on Windows terminal or previous lazygit versions.

I have the same bug on native linux (cachyos) on KDE using Konsole.

I first thought ESC was not working at all, thanks to your issue found out it is only delayed.

This is a regression in the tcell library that we use. It has already been reported upstream, and I linked this issue there; see gdamore/tcell#1169.

[driuba]

Can we expect a patch to revert tcell version change? Or are we gonna wait for upstream fix?

[mauroporras]

Same thing happening on macOS Tahoe 26.6.2 + Ghostty 1.3.1

Thanks.

[stefanhaller]

@mauroporras I'm surprised by that; I don't have this problem with the exact same versions of macOS and Ghostty.

Anyway, can those who are affected by the problem please test the branch wip-bump-tcell in this repo? I confirmed that it fixes it for me with WezTerm on Mac. (Akthough I could imagine that pressing is Esc is still a tiny little bit slower than with 0.64, but it's hard to be sure.)

[driuba]

I'll probably have an opportunity to test it no sooner than tuesday.

On linux (also wezterm), it's much better on wip-bump-tcell, although the response still seems delayed to me (an extra ~50ms compared to 0.64.1).

[appenzellergeller]

Can confirm, on wip-bump-tcell its definitely better (and I would say usable) again on linux in konsole.

But, also, it is definitely not as snappy as it was with 0.64.1. There the ESC action triggered immediately on keydown, now with the fix it is a definitely a bit delayed.

[mauroporras]

@stefanhaller, I should have mentioned that I use the Ctrl + [ combination, just like in Vim. Normal Esc key works as expected. My bad.

[stefanhaller]

@stefanhaller, I should have mentioned that I use the Ctrl + [ combination, just like in Vim. Normal Esc key works as expected.

@mauroporras I'm very confused; normally ctrl+[ shouldn't work the same as Esc with a Terminal that supports modern keyboard protocols (like Ghostty). And it doesn't for me. You'd have to explicitly map it in the lazygit config with something like

keybinding:
  universal:
    return: [<esc>, '<ctrl+[>']

Did you do that? But if I do, it is still very fast.

[mauroporras]

@stefanhaller, I have this config on my config.ghostty file:

# Esc
keybind = ctrl+[=text:\x1B

[stefanhaller]

@mauroporras I see; I can reproduce it with that. And the fix in wip-bump-tcell makes it a lot faster again, but not quite as fast as it was before 0.65.

[mauroporras]

@stefanhaller, I just tested myself and wip-bump-tcell works for me too and such short delay is not a show stopper for me. Thanks for everything.

[stefanhaller]

Ok, this should fix it for real: #6011. Please test this, I'd like to release this tomorrow.
