Tasks dont show full output when terminal is small

[kevindiclemente]

Issue Type: Bug

Tasks don't display the full output from a shell command when the terminal is small, it will also glitch scroll down on task start. Happy to provide a repro, kedicl@microsoft.com

This is likely a dupe of #57803. Since you're on a recent enough Windows build, can you try using the setting "terminal.integrated.windowsEnableConpty": true? It has it's own problems, but it will confirm that #57803 is the cause.

Hi Alex, This still repros even with "terminal.integrated.windowsEnableConpty": true (which seems to only be avaiable in insiders)

[alexr00]

I can reproduce the scroll issue.

If you fix this issue, can you add me to the PR? I'd like to learn more about the code base :) Happy to help fix things as I come across them

I'm seeing the same scrolling behavior in the integrated terminal when using it without tasks. However, I'm not on a sufficiently new enough build to try a stable version of conpty (see #66158, the build number changed). I'll test on the newer Windows Insider build and see if it's still happening there.

This is almost certainly a winpty issue, I'd close as a duplicate of #45693 if it was assigned to me. Conpty should fix it (when people get it).

[alexr00]

In that case, duplicate of #66574.

Thanks for creating this issue! We figured it's covering the same as another one we already have. Thus, we closed this one as a duplicate. You can search for existing issues here. See also our issue reporting guidelines.

Happy Coding!

@alexr00 I was able to unblock myself here by removing a nested bat script:
before: i had foo.bat call bar.bat
now: i invoke bar.bat directly i don't experiance any weird issues
