Apps
Notion
Notion’s desktop app uses Electron and Chromium storage layers to keep workspace content loading quickly, so it accumulates HTTP disk cache entries, V8 compiled code cache, GPUCache data, WebGL and WebGPU shader blobs in DawnCache folders, shared dictionary cache data, and diagnostic logs. Those files speed up page rendering, image reuse, and JavaScript startup, but they can become stale after app, Chromium, or graphics driver changes. Kudu removes those disposable caches and logs while leaving your account, settings, sessions, and offline workspace data intact.
Why clean Notion?
- Outdated V8 compiled code after a Notion update can make the first launch or first workspace switch feel unusually slow until the bytecode cache is rebuilt
- Corrupted HTTP cache entries can leave pages showing old icons, broken cover images, or attachments that spin forever even though the content exists online
- A graphics driver update can invalidate GPUCache and Dawn shader blobs, causing black panes, flickering embeds, or lag when opening databases and board views
- Stale partitioned web cache under Notion’s embedded browser context can break sign-in popups, integrations, or embedded previews that load blank inside the app
- An oversized Shared Dictionary cache can waste disk space and contribute to repeated redownloading when compressed web resources no longer match the saved dictionary data
- Accumulated log files make the profile larger over time, which is noticeable as extra disk usage even though logs do not help day-to-day workspace editing
- Bad cache state can trigger repeated hard refresh behavior where the desktop app keeps showing outdated content until local cache files are cleared and fetched again
