Control key getting "stuck" for enter/tab key?

[JeffMill]

Windows Terminal version

1.18.3181.0

Windows build number

10.0.22631.0

Other Software

No response

Steps to reproduce

Winget install ‘KDE.Kdiff3’

Open razzle (not sure if this matters)

Git config --edit --local

[diff]
    tool = kdiff3
    autoRefreshIndex = true
[difftool]
    prompt = false
[difftool "kdiff3"]
    path = C:/Users/jeffmill/AppData/Local/KDiff3/bin/kdiff3.exe
    cmd = \"C:/Users/jeffmill/AppData/Local/KDiff3/bin/kdiff3.exe\" \"$LOCAL\" \"$REMOTE\"

(modify paths accordingly, of course)

git difftool 66f7252e212f6~1..66f7252e212f6

(use a suitable diff that contains multiple changes in it)

Kdiff3 will open and block the console.

Focus on terminal window and press Ctrl-Break

Focus on Kdiff3 window and press Ctrl-Q

Focus on Terminal window and Press Enter a bunch of times – you should see “mmmm”

Expected Behavior

enter key should work as expected.

Actual Behavior

mmmm is shown.

Probably some weird interaction with msys and console modes here, but at least there's a consistent repro 🤷

Note to self: On the Framework, Fn+b is ctrl+break

I've been really frustrated with what I think might be this same bug for a very long time and finally figured out what reliably repros this for me. Plus, I figured out a (relatively) minimal way to get back to working state, but it's still really annoying.

My Terminal version: 1.18.10301.0 Windows version: 10.0.22631.3085

My symptom sounds a bit different, but similar to title of this issue, so I suspect it might be the same issue.

Symptom: Modifiers seem stuck in a weird state when using some keys, like backspace, arrow keys, home or end. Tapping all control/alt/shift/windows keys doesn't reset the state.

Only easy reset I've found is to launch a sub-cmd process, then exit that sub-process. Then keys are back to normal.

Repro: Set vscode as your editor in git like so:

[core]
	editor = code --wait

Launch editor through git:

> git config --edit --global

Close config file and return to terminal.

Some keyboard keys are now messed up (Backspace, arrow keys, home, end).

Here's what it types now if I hit up, down, left right, space, ctrl-up, ctrl-down, ctrl-left, ctrl-right, space, home, end:

^[[A^[[B^[[D^[[C ^[[1;5A^[[1;5B^[[1;5D^[[1;5C ^[[H^[[F

Backspace will act as ctrl-backspace deleting whole word instead of one character.

Restore normal keyboard behavior by typing:

> cmd
Microsoft Windows [Version 10.0.22631.3085]

> exit

@tex3d Your issue is different (I think). That behavior is typically the result of an application setting the ENABLE_VIRTUAL_TERMINAL_INPUT mode (see SetConsoleMode) and then not restoring the initial state when it exits.
