Chinese input duplication and Vim normal-mode input regression in VSCode 1.101

[FomalhautLeo]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.101.2
• OS Version: Windows11 24H2

Steps to Reproduce:

After upgrading to VSCode 1.101, I’ve encountered two input-related regressions that did not exist in 1.100:

Duplicate text with certain Chinese IMEs
When I type Chinese characters using some input methods, the characters appear twice on screen.

For example, typing “知道” results in “知道知道”.

Vim plugin normal-mode input glitch
In Normal mode (using the VSCodeVim plugin), when I type a letter it shows up in my IME composition window (before committing). Pressing Esc to cancel the composition unexpectedly replaces the character under the cursor with the letter I typed.

These issues force me to roll back to 1.100 and disable automatic updates to maintain a usable environment. Please let me know if any part of this is unclear—I’m happy to provide more information.

Might be duplicate of #251608 or #251809.

Toggling the setting editor.experimentalEditContextEnabled is a workaround.
