@hiromasat Is this still a problem on latest VS Code? (I can't reproduce anymore)

@hiromasat Could you please give steps on how to configure the Japanese input mode in the same way as you are using it? Also, could you please tell me the exact keys you are pressing? Some steps similar to https://github.com/microsoft/vscode/wiki/IME-Test#windowsmac-japanese would be helpful (note the level of detail in the steps)

Sorry for being late to reply. Here is information regarding this issue.

1. Japanese text setting
   Mac setting>Keyboard>Input source>
   Press [+]button to add Japanese Input Source

2. Switch Input source

3. Typing keys
   「日本語入力が揺れている」<- nihongonyuuryokugayureteiru

If you need any other information , I could share them.

@hiromasat Which Japanese input mode should I add?

I have tried with the first one and I can't observe flickering when typing 'nihongonyuuryokugayureteiru':

I used Romaji mode.
Here is my setting about keyboard.

I found the reason of the problem. It comes from extension "Vim"
I uninstall this extension and then the problem disapeared.

So I think that this issue can close.
I'm sorry to trouble you.
