Disappearance of characters and whole lines when opening multiple terminals

[imblowfish]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.73.1
• OS Version: Ubuntu 22.04

Steps to Reproduce:

1. Open multiple terminals
2. Go to last created, write something
3. Go to any other than the last one
4. Write the beginning of a command and press tab for autocompletion

After a while, the characters reappear if you run any command again.

I found this issue #165969, but according to the description it is not entirely clear which input the author means

Here is what I was able to reproduce (In each terminal I enter the same command cd ~/ and press Tab):

I cannot repro on mac, maybe something has been fixed?

[meganrogge]

also can't repro on WSL

[meganrogge]

I believe this is already fixed, can you see if you can reproduce in the Insiders build?

Hi @meganrogge, I don't know if the problem occurs on MacOS
I tried to reproduce this error in the Insider build (Visual Studio Code CLI 1.74.0) and got the same result.

I also recorded a video of how I reproduced the bug, I hope this helps

issue #165969

I saw your problem and it seems that there is something different from mine.

The problem with me was that if I first run the vscode after booting and type in my native language, Korean, some letters disappeared from the input.

There is no problem when typing in English.

For example, if I type '가나다라마바사' in a markdown or any file, some of the inputs disappear and become '가나라바사'.

It disappears even though I typed "다, 마"

@imblowfish Isn't your problem that the terminal input disappears?

@meganrogge Is this issue the same as the issue I opened? #165969

Hi @ZeroOnePro, I think not, my problem is reproduced only in the terminal, there are no problems in the files.

Hi @imblowfish

I wonder if the cause of your problem and the cause of my problem are the same.

What's your idea?

Can't say with certainty

I saw sometimes, though I never found a reproduction for it. However I have not seen it this week, thus marking verified.
