Fixing VS Code UI Unresponsiveness Caused by GitHub Copilot Extension
This article shows a simple solution to a problem that doesn’t seem to be adequately documented: VS Code UI lags, freezes, and delays caused by the GitHub Copilot extension.
Problem: VS Code UI Becoming Slow Having worked on a Python project for a while, I noticed that VS Code’s UI was frequently freezing for seconds at a time. This was happening in various places of the UI: the editor itself but also in the GitHub Copilot Chat window. Copilot also seemed to be taking more and more time getting ready to answer, and the extension-host process would fully saturate one CPU core for long periods of time.
