I&#x27;m not even talking about large files -- I&#x27;m only talking about normal interactions on small (1-10KB) files. Moving the cursor around in the text field, especially when my language plugin is in some mode that has some dialog up on the screen. Find and replace. Switching between open files. All of these operations often (but not always) demonstrate noticeable lag between keyboard input and screen output in VS Code (and Atom, of course).
