Get this decoration left behind

Is this on Windows?

This may or may not be a bug depending on what tsc does exactly when not preserving watch output.

Hints? Prompt locations are not in order

When it's broken, some jumps go out of order when hitting the ctrl+up/down keys. I had assumed it searched the text for the new prompt ansi escapes, so that is weird.

If you can see this horizontal gray bar (real tiny)

Steps to Reproduce

• Open a fresh Powershell Extension terminal
• Enter a few commands
• Hit ctrl+l

It seems to stay broken until you reload

I believe we clear the decorations when certain erase in display sequences happen.

@Tyriar How do I can capture or log the actual ansi escapes sent to the terminal? I can't find it in default settings.json, but I thought I saw it in the patch notes?

I'm looking for that to test whether it's the actual buffer that's out of order -- or if it's at the visual level

Sorry about the long post. I tried to keep it short.

[Tyriar]

@ninmonkey you can run the toggle escape sequence command, checking that for what sequence is clearing is the first thing I'd do

[AffluentOwl]

So where exactly is this magical toggle escape sequences command?

[meganrogge]

That has been removed. You can access that now by running Developer: set log level -> Terminal -> Debug and then open the terminal output channel.

[AffluentOwl]

For future readers who need as much handholding as me. Developer: set log level is a command that can be found by searching in the command palette (Ctrl + Shift + P) for >Developer: set log level. And the terminal output channel can be found in the Output tab (Ctrl + Shift + U) of the Panel area.

It's very possible this will be fixed when conpty v2 lands #224488
