Terminal hangs constantly while running WSL 2

[lumbytyci]

Windows Terminal version

1.19.10821.0

Windows build number

10.0.22631.3447

Other Software

WSL version: 2.1.5.0
Kernel version: 5.15.146.1-2
WSLg version: 1.0.60
MSRDC version: 1.2.5105
Direct3D version: 1.611.1-81528511
DXCore version: 10.0.25131.1002-220531-1700.rs-onecore-base2-hyp
Windows version: 10.0.22631.3447

Steps to reproduce

1. Open Windows Terminal
2. Launch WSL 2 (I'm running Debian)
3. Do some work, usually happens after I save and quit from vim or any console application that has some kind of CLI
4. Windows Terminal will hang (not freeze, there is no Program Not Responding message).

This will happen every few minutes or so. When this happens I have to wait ~30 seconds for the terminal to become responsive. Once responding, all of the previously buffered inputs will flush into the terminal.

Recently I discovered a way to immediately make the terminal responsive once it starts to hang. I do this by sending a SIGINT/Ctrl + C which immediately registers in the terminal (^C) and afterwards zooming in or out (ctrl +/-) - this seems to do the trick.

I'm directing this issue to this repository as opposed to the WSL repository since this issue is not reproducible with other terminal applications.
I can observe this identical issue in both of my devices running Windows 11.

Expected Behavior

Windows Terminal should not hang

Actual Behavior

Windows Terminal hangs

Any chance you can narrow down the repro steps at all? A specific set of commands you're running to make this happen would be helpful, or maybe more info about your vim setup? I know there's at least one other thread around here where IIRC, there's some vim plugin that seems to cause the Terminal to hang.

Another thing that may be helpful to know - does this repro with the vintage console host, conhost.exe/?

I'll do my best to find an exact scenario to reproduce this issue. Is the terminal storing some kind of logs which I could extract and share here?

Funny enough, just as I read your remark I opened the legacy command line application conhost.exe and launched WSL 2 by typing debian and as soon as it launched - it immediately froze. In contrast with windows terminal, zooming didn't fix the problem here. I should note that I have neofetch configured to run in this device once I launch the terminal.

This makes me wonder whether the problem is actually with the windows terminal at all. I will try to mess around and will close the issue if nothing interesting is found.

I have same issue - after installing WSL2 and adding ubuntu as a shell - both Command Prompt and Windows PowerShell would often freeze when typing a command. they would stay frozen for a long time and might unfreeze. I also have Docker Desktop installed and I do some docker builds/etc.

conhost.exe shell works without these "freezing" problems.

@kutovoy I decided to not follow-up with the issue since I am less confident that this is a microsoft-terminal issue. I get similar behaviors on other applications now, one I'd like to note is freezing of chrome.exe when I paste from the Windows 11 clipboard manager. I'm not sure where to start hunting for this issue since it's on Windows.
