Hyper: Sometimes pressing ESC key takes a while to get response

[LexSong]

• [x] I am on the latest Hyper.app version
• [x] I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: Windows 10
• Hyper.app version: 2.0.0(Stable)
• The issue is reproducible in vanilla Hyper.app: Is Vanilla

Issue

Sometimes pressing Esc key will take a long time to get response.

The reliable way to reproduce it is:

1. Run windows version vim with vim
2. Press i into insert mode
3. Type test
4. Press <Esc> key to leave insert mode. It will take roughly a second.
5. type :q! to leave vim
6. Even after leaving vim, <Esc> key still take a while to register. Random typing anything and <Esc> key will take a while to clean the cmd command line.

Reload won't fix it, only full reload with Ctrl-Shift-F5 can reset this behavior.

I can reproduce this issue in the demo app of xterm.js.

Looks like an upstream issue

Am also getting this issue

Testing the terminal timeout tweak in this post seems to fix this. I am only getting this issue when ssh'd to outside servers. This only popped up recently, it's been working fine for a while.

I get this too - but not when I first open a terminal and SSH out. It happens over time.

I'm using WSL as my base shell

This also happens to me over time.

I love Hyper - it's the best terminal experience I've found for Windows.
This is pretty much a deal breaker for me though.

I end up eventually finding myself pounding ESC over and over again in VIM
trying to get out of insert mode :(

I have the same issue.

I have never used hyper, but just for information I can share that I'm having similar problem with ESC taking about 1 second to register.

My setup is: WSL (Windows Subsystem for Linux) with Ubuntu -> ssh -> tmux -> nvim

Not clear if this is on hyper or ubuntu.exe?

@LexSong @ecielam @jamessewell @uadev
Is it still happening?
Can you try out the ci build once also (lots of improvements since last release)

I had this issue and narrowed it down to a tmux config problem:

Fix it by adding set -sg escape-time 0 to ~/.tmux.conf

You can apply it without restarting tmux by:

<C-b>:source-file ~/.tmux.conf (or substituing <C-b> for your tmux control key)

Hi, sorry for the late reply

I can confirm that this issue no longer exists.
I'll close this issue.
