Notion
Notion’s desktop app is built on Electron and keeps several browser-style caches on disk so pages, avatars, icons, scripts, and rendered assets load faster between sessions. It accumulates HTTP disk cache entries, V8 compiled code cache, GPUCache data, WebGPU and Dawn shader blobs, partitioned web cache for embedded content, shared dictionary cache, and diagnostic logs; Kudu removes those temporary files while leaving your workspace data, login sessions, settings, and offline content alone.
Why clean Notion?
- Corrupted HTTP cache entries can make Notion pages show outdated covers, missing icons, or broken embeds even after a hard refresh
- Invalidated V8 compiled code after a Notion or Electron update can cause an unusually slow first launch, repeated renderer restarts, or sluggish page switching until the cache rebuilds
- Stale GPUCache files after a graphics driver update can trigger blank windows, black sidebars, flickering, or choppy scrolling in the editor
- Old Dawn and WebGPU shader blobs from a previous app or driver version can cause stutter when opening databases, whiteboards, or media-heavy pages and may crash the renderer on startup
- Partitioned cache for embedded content can preserve bad copies of third-party widgets, so a synced page loads but specific embeds stay blank, loop forever, or ignore recent changes
- An oversized Shared Dictionary cache and accumulated web cache can consume hundreds of megabytes of disk space while Notion feels no faster, especially on systems with small SSDs
- Growing log files can quietly fill profile storage after repeated sync, sign-in, or renderer errors, leaving users with disk warnings and harder-to-diagnose launch problems
