Cursor IDE Partitions
Inside Cursor’s Partitions folder, the IDE stores Chromium-based browser profile caches for embedded webviews and workspace surfaces, including HTTP disk cache entries, Code Cache V8 bytecode, GPUCache data, and shader cache files used to speed up UI rendering and web content startup. These files are regenerated from app resources and network responses, but they can become stale after Cursor updates, extension webview changes, or graphics driver changes. Kudu clears those disposable partition caches while leaving sessions, logins, settings, and other persistent web data intact.
Why clean Cursor IDE Partitions?
- Stale Code Cache bytecode after a Cursor or extension update can make panels open slowly or briefly render blank until Chromium recompiles the webview scripts
- Corrupted HTTP disk cache entries can leave the account page, extension marketplace, or embedded docs showing outdated content, broken styling, or endless loading spinners
- GPUCache data invalidated by a graphics driver update can cause flickering UI, black rectangles, or sluggish redraws in hardware-accelerated parts of the interface until the cache is rebuilt
- Old shader cache blobs from a previous GPU or driver state can trigger stutter when opening terminal, editor, or settings surfaces that rely on accelerated Chromium rendering
- Oversized partition caches consume AppData space and can make Cursor feel inconsistent across launches, with some webview-backed features loading instantly and others hanging while bad cache entries are retried
- If a partition database uses SQLite internally, page fragmentation can waste disk space and slow cache lookups; VACUUM rewrites the file into a compact layout without deleting your actual saved data
