Apps
Bitwarden
Bitwarden’s desktop app is built on Electron, so it keeps Chromium disk cache entries in Cache/Cache_Data, V8 bytecode in Code Cache, and GPU-rendering data in GPUCache to speed up vault UI loading, icon rendering, and web content used inside the app. Those files can become stale after Bitwarden, Electron, or graphics driver updates, leading to odd interface behavior or wasted disk space. Kudu removes only these disposable caches so the app can rebuild them cleanly without touching your vault data, account, settings, or saved login state.
Why it matters
Why clean Bitwarden?
- Invalidated Electron V8 bytecode after a Bitwarden desktop update can make the first launch feel unusually slow while the app recompiles its interface code
- Corrupted Chromium disk cache entries can leave the login window, vault list, or embedded web views partially blank until the cache is rebuilt
- Stale GPUCache data from a graphics driver update can cause flickering, black panels, or sluggish rendering in the Bitwarden window
- An oversized Cache_Data folder keeps old HTTP resources and app assets around, wasting disk space even though Bitwarden can safely download or regenerate them
- Broken cached frontend assets can make icons, fonts, or theme elements render incorrectly, so the app looks inconsistent until those files are cleared
- GPU shader cache mismatches can increase stutter when opening or resizing the Electron window because Chromium has to recover from invalid rendering state
