I have used VSC for 2 years, and never meet this problem before. (I'm not sure if it is related to the version).

And this troubled me a lot, because I need to communicate with workmates in Chinese and write code comment in Chinese. I have to switch language frequently. My solution is reopen the file, in a conclude, this bother me a lot.

But now I find a perfect solution. Thanks @byyxx128 , your comment inspired me. I find in QQ IME setting as below. The red block means 'Input the holder text when switch language'. And everything's fine when I checked this radio.

However, not all IME support this function, so I'm sure there is a few people are suffering.

[Eve-Sama]

I just know QQ IME has own group. I will submit a application for joining and feedback this issue. And my QQ IME can't update automatically, and this issue happens rencently. Therefore I still keep a doubt for VSC.

[rebornix]

It sounds like an issue with QQ IME as mentioned above it happened in other applications too. Is there any link to the issue report to QQ IME?

[Eve-Sama]

@rebornix Thanks a lot to check this issue.

This problem should appear in the past time if the reason is related to QQ IME. Because I have never update the version of QQ IME. And I have reported this issue to the official group of QQ IME.

Have the some problem with microsoft IME. It happen to keystrokes that doesn't trigger compositionupdate event during composition.

It seem like it's because compositionend doesn't fired when switching input mode. Maybe it's a chrome issue?

[Eve-Sama]

It make sense! Should I close this issue?

I'm using Windows 10 built-in 微軟新注音輸入法(Microsoft New Phonetic IME). I'm suffering from this issue as well. I just record a short clip to demonstrate this issue on my PC.

1. type in English is no problem
2. type in Chinese without modification is fine as well
3. type in Chinese but fixing typo during input, then switch IME back to US Keyboard. The editor will become strange.

I just confirmed this doesn't happening in VSCode 1.39.2. It's happening after VSCode 1.40.0.

[Eve-Sama]

You can try to find some input settings via IME to solve this problem. @doggy8088
BTW, The world is very small... I will see u in ngChina2019 : )

[doggy8088]

@Mr-Eve I can't find any settings related to this problem. This is definitely a bug. Any suggestion?

See you soon! 😄

[Eve-Sama]

@doggy8088 This problem really effect the state of work. I guess u wanna solve it as soon as possible.

Temparerily, u can switch another IME as a solution, u can find some settings based on the words of @byyxx128 .

[doggy8088]

@Mr-Eve No no, I already solved this issue by downgrade my VSCode to 1.39! 😄

[doggy8088]

Could be. @rebornix

[jasonlyu123]

@rebornix I found this problem also appear in the embed chrome dev tool. Maybe we'll just wait for next electron version bump and see if the problem persist.

(just ignore the typo in the screenshot lol)

[doggy8088]

@jasonlyu123 I can confirm that in my Chrome version 78.0.3904.97 and 78.0.3904.108. Did you see any upstream issue been opened?

[ck97756]

I have this issue too.
VS Code version: 1.40.2

[doggy8088]

After I upgrade to 1.41.0, this issue still exists. 😒

[doggy8088]

@rebornix Do you have any upstream issues information?

[doggy8088]

@Mr-Eve 你的標題有個錯字，是否可以請你修正？ Swich -> Switch

[Eve-Sama]

@Mr-Eve 你的標題有個錯字，是否可以請你修正？ Swich -> Switch

OK, thanks for reminding

[rebornix]

Can anyone help confirm that you can see this issue in Dev Tools of latest Chrome? If so I can try to find an upstream issue and also see how to fix from our side with Electron.

[doggy8088]

@rebornix I record a short video for you. Please check this out: https://youtu.be/PzRPH7hQmh8

[rebornix]

@doggy8088 thanks! It looks like a chromium bug. We should validate this once we adopt a newer version of Electron. cc @deepak1556

In vscode 1.43.2:
when windows 10 version 18363.720, no issue
when windows 10 version 19041.172 (insider), issue still exist
using Taiwan's Microsoft Bopomofo IME

[doggy8088]

@abc1236762 I'm using windows 10 version 18363.720 and vscode 1.43.2. There are still does have issue. I'm using Taiwan's Microsoft Bopomofo IME.

[abc1236762]

in vscode 1.43.2 and windows 10 version 18363.720, the issue exist again to me, and when I reopen vscode, no issue.
seems sometimes happened to me, sometimes not, I cannot find out the conditions.

[peienxie]

when I upgraded to vscode 1.45.0 the issue is gone
switching between Chinese and English works perfect

[doggy8088]

@peidaqi I don't think so. I still have this problem in my VSCode 1.45.0.

[jasonlyu123]

As @abc1236762 said. we don't know how to reproduce the issue. It just sometimes happened and resolved after restarting vs code.

We could either

1. find a way to reproduce it and found a workaround or report to the chrome team.
2. Just wait for a long enough period of time after each release and see if it resolved.
   if most people on this thread agreed on it resolved, just close this.

[doggy8088]

@jasonlyu123 I can reproduce the problem anytime. If I know how to report to upstream, I can do the work, but I don't know where I can report to.

[jasonlyu123]

how do you reproduce it? maybe we could at least try to found a workaround.

[doggy8088]

@jasonlyu123 Check this out: https://youtu.be/PzRPH7hQmh8

[doggy8088]

I think @rebornix already know this. https://github.com/microsoft/vscode/issues/84449#issuecomment-578907589

[jasonlyu123]

I didn't notice that was the way to reproduce it. Sorry

[jasonlyu123]

@doggy8088 保哥：
我試了一段時間終於發現要怎麼重現你的問題了，沒有發現你是切換輸入法，切換輸入法或是用游標切換中英模式幾乎百分之百可以重現問題，我在 chromium 的 edge 中也可重現一樣的問題，但可能是因為我大多是用 shift 鍵切換中英模式所以問題很少出現。

[doggy8088]

@Mr-Eve I think this issue has been solved by recent versions.
