If you are thinking of issues #7091 and #6634 note that the output processing differs and that they aren't running on WSL.

This doesn't look like the stock zsh configuration. Can you share your zshrc?

Yes I'm using a custom zshrc and the PROMPT is here https://github.com/skyline75489/mydotfiles/blob/master/.zshrc#L41

This also happens with conhost. What interests me is that, in the OpenSUSE WSL distro which I mainly use, the issue does not exist. Be it zsh on bash, bash on bash, you name it. It all works. But in the Ubuntu WSL2 distro it collapses for some reason.

When I'm finished with the OSC things I'll see if I can find out why.

Now that I think about it, it may be just my zshrc is broken since it contains invisible characters. Maybe just a false alarm.

OK I can confirm it's a false alarm. Something happens to my local zshrc file. It no longer contains actual \e escape codes any more..

Maybe it's just me doing some copy-paste thing that ruined the zshrc in the past but I didn't realize that. Never mind. Still a false alarm.

It's a lot easier to instead use the Z shell's built-in mechanisms for coloured prompts, e.g. %F{green}, %B, %b, and %K{254}. One does not have to calculate or hardware any control sequences at all, and this problem does not occur.

@skyline75489 are you using zsh from Windows like git-bash or WSL2?
