Conemu: Delay in response to any keypress in Git Bash/Ubuntu Bash prompt

[akittas]

Versions

ConEmu build: 171117 x64
OS version: Windows 1709 x64
Used shell version (Far Manager, git-bash, cmd, powershell, cygwin, whatever): Windows Bash, Git Bash

Problem description

There is a delay in response to any keypress (like I'm typing at some remote terminal). This appears in git bash or windows ubuntu bash prompts, but not in a normal windows cmd prompt. This issue appeared in version 171117 and does not exist in version 171109.

Steps to reproduce

1. Open Conemu.
2. Start a git bash or ubuntu bash shell.
3. Start typing any command. Try holding a key pressed and observe how slow the characters are repeated. Compare this to a windows cmd prompt, keys are repeated fast and there is no delay when a key is pressed.

That is because connector acts as "remote terminal". Previous version, which had no lags, had much worse problem - freezed input.

Um... so what does this mean? Can it be solved?

[akittas]

Yes this is really unfortunate.. Having either the chance for freezed input or a prompt with a constant lag :(

[akittas]

I'm using at the moment 17.11.09 and have not experience any freezed input yet, and the bash/git bash prompts work well with no lag. Maybe this can be incorporated in future versions? 17.11.17 feels very laggy for git bash/bash prompts, I'm actually surprised that more users are not reporting this. It really breaks the experience when typing in the terminal.

[Maximus5]

It's upon a chance when your terminal freezes in 171109. And it occurs always on rapid typing.

@Maximus5 Is there anything we could help solving this issue though?

Because the lag really is quite unbearable for me - it feels like it takes about one second for each keypress to take action. If I connect to a remote machine using SSH there's no additional perceivable lag apart from the natural one, which makes me whonder why the connector causes such issues even though it's running locally, right?

Edit: I know that I can revert the Bash task to the old one (wsl.exe -cur_console:pm:/mnt), but that's not really a solution isn't it?

[akittas]

I have to second @lhecker, the lag is really making the bash prompts (and by extension ConEmu) unusable for me.

@Maximus5 from some quick tests I did it seems it is fixed in 17.12.03. This is great!

@Maximus5 This seems resolved in 17.12.03 for me as well.
