NVDA Laggs a lot in Visual Studio Code editor while typing and reading the code #11533

Description

@akash07k

Steps to reproduce:

  1. Open Visual studio code.
  2. Open a file or directory containing any text files in it such as a javascript/python project.
  3. Go to the editor.
  4. try navigating the text/code via arrow keys.
  5. Now try typing some code in the editor quickly.
  6. It will be observed that in both 4th and 5th point, NVDA laggs a lot while navigating and typing the code in the editor.
  7. Now repeat the same thing with Notepad plus plus or another text editor.
  8. It will be observed that NVDA doesn't lag there at all and responds very snappily.

Actual behavior:

When we navigate/read and type the text/code in visual studio code editor, NVDA laggs a lot and responds very slowly.
For example, If we navigate/read the code in notepad NVDA responds/reads every line quickly but in VS Code, it doesn't happen like this.
Also, If we quickly type the code, most of the times, NVDA announces the typed characters after a delay which is very annoying and problematic.
It doesn't happen with other applications.

Expected behavior:

NVDA should not lag in VS Code editor and should be responsive like it is with other editors.
