Cursor IDE
Built on Electron and the VS Code architecture, Cursor IDE writes Chromium HTTP disk cache files, V8 code cache and CachedData bytecode, GPU shader and render caches, cached extension artifacts, and rotating log files to speed startup, webview rendering, and extension loading. Those caches can become stale after Cursor updates, extension changes, or graphics driver changes, leading to odd UI behavior and wasted disk space. Kudu removes only disposable cache directories and settled logs while leaving projects, chat history, sessions, extensions, accounts, and settings untouched.
Why clean Cursor IDE?
- Invalidated V8 code cache and CachedData after a Cursor update can make the first launch crawl or leave windows sitting on a blank splash before the bytecode rebuilds
- Corrupted Chromium Cache_Data entries can cause Marketplace panels, settings search, sign-in pages, or extension webviews to load partially, show outdated content, or spin forever
- Stale GPUCache data from a graphics driver update can break hardware-accelerated rendering, causing black editor panes, flickering menus, or laggy scrolling until shader caches are regenerated
- Old CachedExtensions artifacts can keep extension host resources out of sync after an extension update, leading to missing icons, broken language features, or repeated extension reload prompts
- Accumulated logs from crashes, extension host restarts, and background services can grow quietly over time and waste disk space while providing no benefit once the issue has passed
- Bloated Electron disk cache can keep obsolete copies of remote assets and webview resources, which shows up as stale UI elements, mismatched themes, or slow reloads of built-in panels
- Cursor stores some internal state in SQLite-backed files, and over time page fragmentation can waste space even without new data; VACUUM rewrites the database into a compact file without deleting rows, while Kudu avoids your actual project, history, and settings data
