Typed input is sometimes wrongly ordered

[Vampire]

Windows Terminal version

1.20.11781.0

Windows build number

10.0.19045.3930

Other Software

Bash from Git for Windows

Steps to reproduce

I cannot tell exactly how to reproduce.
But it happens regularly.
The prompt is not ready yet because it still executes the last command or evaluates the PROMPT_COMMAND of Bash.
Then I already type the next command like git b -a (b here is a Git alias for branch -vv).

Now regularly it happens that once the prompt is ready what is inserted is misordered, like agit b -, so the characters typed later are input before characters typed earlier.

I first thought I just mistyped, but I'm absolutely sure now, that I did not mistype, but the characters were not inserted in the order I typed them.
I guess there is some race condition somewhere that causes this.

Expected Behavior

Input appears in the order I typed it.

Actual Behavior

Input is mixed up.

• Does this repro outside of Git for Windows?
• Did this repro on older versions of the Terminal?
• What version of git for windows / bash/?

Our current hypothesis is that this is something weird that cygwin is doing, but it's hard/impossible for us to investigate without a more consistent repro

Does this repro outside of Git for Windows?

I almost exclusively use Bash from Git for Windows as shell, so I don't know.

Did this repro on older versions of the Terminal?

I'm not 100% sure, but if it happened, then not that often that I felt like reporting it and I'm usually fast with reporting issues.

What version of git for windows / bash/?

Just updated 2 hours ago to 2.46.0.windows.1, I think it was 2.45.0.windows.1 before.
as I just upgraded it and did not do much work since then, I don't yet know whether it still reproduces.

Our current hypothesis is that this is something weird that cygwin is doing,

That's quite unlikely, as Cygwin is not at all involved. :-D
Git for Windows is MSYS-based, not Cygwin-based. :-)

it's hard/impossible for us to investigate without a more consistent repro

Totally understand that, I'm just not able to provide a better or more reliable reproduction recipe for this. :-(

Ah, but MSYS is itself Cygwin-based! 🙂
