Obsidian
Built on Electron, Obsidian stores Chromium disk cache entries, V8 compiled code in its Code Cache, and GPUCache data such as rendered asset caches and shader-related blobs to speed up startup and interface rendering. These files help the app load vault views, plugins, themes, and embedded web content faster, but they can become stale after Obsidian, plugin, theme, or graphics driver changes. Kudu removes only those disposable cache folders, leaving vault notes, attachments, settings, accounts, and community plugin data intact.
Why it matters
Why clean Obsidian?
- Invalidated V8 bytecode after an Obsidian or plugin update can make the app pause on launch or feel unusually slow until the Code Cache rebuilds
- Corrupted Chromium disk cache entries can leave the Community Plugins or Settings interface partially blank, with missing icons, styles, or panes that do not render correctly
- Stale GPUCache data from a graphics driver update can cause flickering, black panels, or sluggish redraws when switching notes, sidebars, or graph view
- Accumulated cache files from repeated theme, plugin, and embedded content loads can grow to hundreds of megabytes, taking disk space while providing little benefit after updates
- Old cached assets can make Obsidian keep showing outdated plugin UI resources or theme elements, so buttons, fonts, or colors look wrong until the cache is cleared
- Broken cache state in Electron can cause embedded web content such as plugin storefront pages or help content to load inconsistently, with blank sections or repeated refreshes
- A first launch after cleaning may be slightly slower, but it often resolves persistent startup hangs and rendering glitches without touching vault contents or preferences
