Bitwarden
Bitwarden’s desktop app is built on Electron, so it keeps Chromium-style disk cache files in Cache/Cache_Data, JavaScript and renderer bytecode in Code Cache, and GPU rendering artifacts in GPUCache to speed up vault UI loading, icon rendering, and hardware-accelerated drawing. Over time these cached web resources, V8 code cache entries, and GPU shader data can become stale after an app or graphics driver update. Kudu removes only those disposable cache folders, not your vault data, account, settings, or saved logins.
Why clean Bitwarden?
- Stale Electron Code Cache entries after a Bitwarden update can make the first launch unusually slow while the app throws away old bytecode and rebuilds it
- Corrupted Cache_Data files can leave parts of the vault interface loading incorrectly, such as blank panes, missing icons, or a spinner that never finishes
- An oversized Chromium disk cache can waste hundreds of megabytes on old bundled assets and API responses even though Bitwarden can recreate them on demand
- GPUCache data tied to an older graphics driver can become invalid after a driver update, causing flickering, black windows, or laggy scrolling until the shader cache is rebuilt
- Broken cached frontend assets can cause the desktop app to show outdated styling or misaligned controls after upgrading to a newer Bitwarden release
- If the renderer keeps reusing bad cache entries, search and vault navigation may feel inconsistent, with delayed screen redraws and temporary blank content before refreshing
