Apps
Notion
Built on Electron, Notion stores Chromium disk cache entries for downloaded page assets, images, and API responses, along with V8 compiled code cache and GPU shader data used to speed up rendering. Those files help pages, databases, and embedded content open faster, but they can become stale after app updates, workspace changes, or graphics driver changes. Kudu removes Notion's Cache_Data, Code Cache, and GPUCache so the app can rebuild fresh temporary data without touching your pages, account, settings, or local content.
Why clean Notion?
- Stale Chromium disk cache can keep serving outdated page assets or API responses, which shows up as pages loading with missing icons, broken cover images, or embeds that never finish rendering
- Invalidated V8 compiled code after a Notion or Electron update causes unusually slow startup and sluggish first opens of pages until the code cache is rebuilt
- Corrupted Cache_Data entries can leave the app stuck on a blank window, endless spinner, or partially rendered sidebar even though your workspace data still exists on the server
- GPU cache blobs from an older graphics driver can conflict with the current one, causing black flashes, flickering panels, or choppy scrolling until Notion regenerates its GPUCache
- Large accumulated cache folders waste disk space over time because Notion stores downloaded images, attachment previews, and web assets locally, which is noticeable on smaller SSDs
- After frequent workspace switching or heavy database use, mismatched cached resources can make relation properties, board thumbnails, or inline media appear out of date until a hard refresh or cache clear
- Embedded web content and previews may fail to load correctly when cached responses expire badly, leading to blank embeds or repeated reload prompts even on a stable connection
