Terminal: Terminal will auto repeat my last input

[xjr7670]

Environment

Windows build number: [run `[Environment]::OSVersion` for powershell, or `ver` for cmd]
Microsoft Windows [Version 10.0.18363.535]
Windows Terminal version (if applicable):
Version: 0.7.3451.0

Any other software?

Steps to reproduce

Expected behavior

Actual behavior

when I input something within the terminal, no matter it is command line or coding with VIM editor in WSL, it will all occur this problem.

For example, I want to key down "cat -n 10 myfilename" in the wsl command line, sometimes when I finished key down the letter "n", I want to continue to write "a", but at this time, The terminal will auto repeating the letter "n" for many many times. I was not able to do anything unless just press the X button to close that window.

I have recorded a video to show this problem

But this will not occur in the system's cmd which opens with "win+r" then write down "cmd" or PowerShell and so on. Only occur in terminal

The system version which I use is:

I cannot search for anything with this problem. Appreciate to get some help

This seems like #3706, but your example indicates that it happens for normal input?

Yes, absolutely normal. I see that issue #3706 was caused by the Chinese character. Or it may occur by the Chinese input software? I am using the Microsoft Wubi from the system. But this problem occurred when I was in English input status.

I started seeing this to on the latest nightlies.

See screenshot. This appears to be a display issue as the commands execute successfully. Here I'm typing "git <enter>" "git checkout <enter>"

The latest store version is fine for me.

I'm experiencing the same as @onovotny
Building from current master (d711d731d7d00259b2e0fe5847928c9f1c1121ed) results in this behaviour.
I reverted to 4daf1d7f9c36eb2129c277e89255d44670db0537 (just because it was the last usable version I built) and don't see that issue, so it may be within that commit range.

Yeah, this is #4107 (PR #4113)

@xjr7670 Are there any other interesting things about your machine that might help us figure this one out? Nobody here's got any idea.

Just FYI - #4107 is a new regression after 0.7, so it is not the cause of this issue.

In addition to the input software, there is a software called DLP. Which is used to monitoring every computer's internet I/O traffic inside our company to prevent information leakage.

After installed DLP, it will auto output some error info to the shell window, especially within the powershell

I can offer something about DLP if you need it. For example the log file or something else.

We have made some changes to the input stack recently. Is this still happening?

[xjr7670]

It has not reappeared recently, it should have been repaired

Thank you!
