VS Code messes up console output

[doctordns]

Issue Type: Bug

This MAY be a bug in the PowerShell extension, but when running Test-NetConnection, results in corrupted output to the terminal. If I run the following command by highlighting it in the editor and Run Selection get corrupted output like this:

When complete the screen looks like this - losing almost all the output

This does NOT happen in the console.

(Experimental duplicate detection) Thanks for submitting this issue. Please also check if it is already covered by an existing one, like:

Thanks @vscodebot. Not sure, but it is a terrible bug that needs fixing. And even if it is a duplicate, you have closed the other report and I can't even comment on it. This bug still exists hence this issue

[Tyriar]

@doctordns can you check if this behaves differently when run inside Windows Terminal?

[doctordns]

I do not have windows terminal installed. This happens on no powershell console.

Do I need to install Terminal to fix this issue? Terminal is not an acceptable solution.

[Tyriar]

@doctordns just trying to root cause the issue so we can get it fixed, if it also reproduces in Windows Terminal then it's an issue with our shared dependency (conpty).

[doctordns]

I will figure out how to download and install the terminal and get back to you. This will take a few...

:-)

[doctordns]

Well - maybe I should have noted that the issue occurs on Server. Unless I am missing a magic incantation - the store does not seem to be in Server. And when I downloaded release from GitHub, there seems no way to install the MSIXBundle file. Do I have to load Visual Studio to compile the source code to use the terminal? :-)

Fortunately, there is a slightly different failure in Windows 10.

Here is what I see in VS Code if I run Test-NetConnection:

SInce the output is so weird an MP4 seemed a better way to show this issue.

As I kind of expected, if I run this from Terminal, i get the following output:

Interestingly, the output in VSCode is different between Server and Win10. But both are borked.

@doctordns I tried locally and it works for me 🤔

Does this happen if you change the value of terminal.integrated.rendererType (try all 3), recreate the terminal and run it again? Maybe it's an issue with one renderer in particular.

[doctordns]

All three fail. I attach an MP4 showing the results

[Tyriar]

I see that you're using the powershell integrated console from the PS extension, does it happen in a regular pwsh shell? It should look like this:

[doctordns]

AHHHHHHHHHH

Yes - it works just fine in the "regular pwsh shell". :-)

So is that a bug with the extension then??

I have opened an issue on the extension too.

[Tyriar]

Seems like it, thanks for creating the issue 👍
