Cursor IDE

Built on Electron and a VS Code-derived extension host, Cursor IDE writes several layers of temporary data to speed up startup, rendering, and extension loading. Those files include Chromium HTTP disk cache entries in Cache_Data, V8 code cache and compiled script blobs in Code Cache and CachedData, GPU shader and raster caches in GPUCache, cached extension package data in CachedExtensions, and rotated diagnostic logs. Kudu removes only these rebuildable caches and settled logs, leaving your projects, settings, installed extensions, accounts, and saved credentials untouched.

Why clean Cursor IDE?

  • Invalidated V8 bytecode after a Cursor or extension 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in Cache_Data can leave the sign-in panel, settings webviews, or extension marketplace views stuck loading or rendering outdated content
  • Stale GPUCache entries from a graphics driver update can cause black editor panes, flickering UI, or choppy scrolling until Electron regenerates shader and raster data
  • CachedExtensions can retain old extracted extension assets after upgrades, which shows up as extensions failing to activate, missing icons, or language features not starting correctly
  • Large accumulated logs from repeated crashes, extension host restarts, or verbose diagnostics can quietly consume disk space and make troubleshooting harder by burying current errors in old sessions
  • SQLite-backed app databases used by Electron-based IDE components can become page-fragmented over time; VACUUM rewrites the file to compact free pages without deleting rows, reducing wasted space and improving locality
  • When multiple stale cache layers build up together, Cursor may feel oddly inconsistent across launches, with slow window restore, delayed command palette responses, and webviews that only start working after a restart
