Cursor IDE
Built on Electron and the VS Code architecture, Cursor IDE stores Chromium HTTP cache files in Cache_Data, V8 code cache and compiled script data in Code Cache and CachedData, GPU shader and render artifacts in GPUCache, extension download and unpack caches in CachedExtensions, and rotating diagnostic logs under logs. These files speed up startup, extension loading, webview rendering, and AI-assisted interface components, but they can go stale after app, extension, or graphics driver updates. Kudu removes those disposable caches and settled logs while leaving projects, chat history, sessions, extensions themselves, settings, accounts, and saved credentials untouched.
Why clean Cursor IDE?
- Invalidated V8 bytecode after a Cursor update can make the first launch hang on a blank or partially drawn window until Code Cache and CachedData rebuild
- A corrupted Chromium disk cache in Cache_Data can break extension marketplace pages, embedded docs, or sign-in webviews, showing endless spinners or missing page content
- Stale GPUCache entries from a previous graphics driver version can cause flickering panels, black editor surfaces, or stuttering in webview-based UI until the shader cache is regenerated
- Cached extension artifacts can accumulate after repeated extension installs and updates, wasting disk space and sometimes causing an older webview bundle to load instead of the current one
- Settled logs keep growing after crashes, extension errors, and AI feature diagnostics, leaving unusually large AppData or Application Support folders even when active projects are small
- Mismatched compiled data for built-in or updated extensions can lead to slow command palette responses, delayed sidebar rendering, or a long pause before notebooks and markdown previews appear
- When Cursor’s cached web assets no longer match the current build, chat panels or settings pages may render incorrectly, with missing icons, blank sections, or repeated reload prompts
