Cursor IDE

Built on Electron and the VS Code architecture, Cursor IDE stores Chromium disk cache entries in Cache_Data for webview and UI resources, V8 compiled script data in CachedData to speed startup, cached extension packages in CachedExtensions, and session log files for renderer, extension host, and background processes. These files help the editor launch faster and avoid repeated downloads, but they can become stale after app, extension, or GPU/Chromium changes; Kudu removes those caches and logs without touching projects, settings, accounts, or saved code.

Why clean Cursor IDE?

  • Invalidated V8 compiled script data in CachedData after a Cursor update can make the first launch unusually slow, with the window appearing late or extensions taking longer to activate until the cache rebuilds
  • Corrupted Chromium disk cache entries in Cache_Data can cause blank settings panes, missing icons, or webview-based features that render as a white or empty panel
  • Stale cached extension packages can leave an extension stuck on an older bundle, showing repeated activation errors, missing commands, or features that do not match the installed version
  • Accumulated renderer and extension host logs can grow unexpectedly during crashes or repeated reconnect loops, leading to large AppData or Application Support usage and frequent disk activity while Cursor is open
  • Old cache artifacts from a previous Electron or Chromium build can cause UI glitches such as flickering panels, broken markdown preview, or sign-in pages that never fully load
  • A damaged cache can trap Cursor in repeated asset fetch and reload behavior, which users notice as slow sidebar population, delayed command palette results, or webviews that only work after a full restart
