Description

Describe the bug
Migrating from Vim to VSCode and this is the first plugin suggested to me so I installed it and gave it a try. I'm not deep into any customizations for VSCode nor do I have any settings for VSCodeVim. I'm just trying to set it up so I can use it.

There are certain keystrokes that has a very noticeable delay. Pressing to go to normal mode has a noticeable dela. Pressing to enter insert mode doesn't have any delay ( and doesn't have delay). Most text modifying commands I tried has a delay: , , . Starting search with </> doesn't have a delay and the incremental search works smoothly but hitting to go to the first hit has a delay.

To Reproduce
Steps to reproduce the behavior:

  1. Install plugin
  2. Activate plugin
  3. Use plugin

Expected behavior
No delays/lag. Smooth operation.

Research direction

The issue names no source files, tests, or entry points. Start by reproducing the delay with VSCodeVim v1.17.1 on VSCode 1.51 and macOS 10.15.7, comparing Escape, text-modifying commands, and search confirmation. Done means the reported keystrokes operate without noticeable lag, with diagnostic evidence identifying the affected path.
