1Password

Built on Electron, 1Password stores Chromium disk cache entries in Cache_Data for web content used by the desktop app, plus V8 code cache and GPU cache on platforms where those components are present. These files speed up rendering of the vault interface, account sign-in views, icons, and hardware-accelerated UI drawing, but they can become stale after app or graphics driver updates. Kudu removes only those temporary cache files so 1Password can rebuild them cleanly without touching vault data, accounts, settings, or secret keys.

Why clean 1Password?

  • Corrupted Chromium disk cache entries can leave the sign-in or unlock window partially blank, with missing icons or panes that only reappear after the cache is rebuilt.
  • Invalidated V8 bytecode after a 1Password app update can cause an unusually slow first launch or a UI that feels stuck while JavaScript recompiles.
  • Stale GPUCache data from a graphics driver update can break hardware-accelerated rendering, showing black panels, flicker, or a window that opens but does not paint correctly.
  • An oversized Cache_Data folder can keep growing after repeated account switching and embedded web view use, wasting disk space even though the cached responses are disposable.
  • Out-of-date cached assets can make the sidebar, item list, or account setup screens display old styling or fail to load parts of the interface until fresh files are fetched.
  • Bad cache state can cause repeated redraws and jerky scrolling in the desktop app, especially when opening large vaults or switching between item details quickly.
