1Password
Built on Electron, 1Password stores Chromium disk cache entries in Cache/Cache_Data, V8 bytecode in Code Cache, and GPU-rendering data in GPUCache to speed up vault views, account switching, icon loading, and hardware-accelerated interface drawing. After app updates, Chromium changes, or graphics driver changes, these temporary files can become stale or oversized and lead to blank panes, sluggish startup, or rendering glitches. Kudu removes only those disposable cache files so 1Password can rebuild them cleanly without touching vault contents, accounts, settings, or saved passwords.
Why clean 1Password?
- Invalidated V8 bytecode in Code Cache after a 1Password or Electron update can make the app open slowly on first launch or pause before the vault list appears
- Corrupted Chromium disk cache entries can leave the sidebar, item icons, or Watchtower content partially blank until the cache is rebuilt
- A bloated Cache_Data folder can waste hundreds of megabytes and cause longer startup while 1Password scans and recreates stale web assets
- Stale GPUCache data from a graphics driver update can cause black windows, flickering, or missing interface elements when hardware acceleration starts
- Bad cached responses inside the embedded app shell can make account switching or sign-in screens load inconsistently even though your vault data is intact
- Removing old Electron cache files helps resolve cases where search, item detail panes, or settings pages render incorrectly despite the app itself being up to date
