Apps
Obsidian
Built on Electron, Obsidian stores Chromium disk cache entries for downloaded vault assets and web content, V8 compiled code in its Code Cache, and GPUCache data such as shader and rendering state blobs used by the app’s accelerated interface. These files speed up startup and UI rendering, but they can become stale after Obsidian, plugin, theme, or graphics driver changes. Kudu removes Obsidian’s Cache_Data, Code Cache, and GPUCache files without touching vault notes, attachments, settings, accounts, or community plugins.
Why clean Obsidian?
- Invalidated V8 compiled code after an Obsidian or plugin update can make the app hang longer on first launch, show a blank window briefly, or feel unusually slow until the cache is rebuilt
- Corrupted Chromium disk cache entries can leave embedded images, remote resources, or plugin-provided web views stuck loading, even though the vault itself and note files are intact
- Stale GPUCache data from a graphics driver update can cause flickering panes, black or transparent UI regions, or jerky scrolling in the editor until Electron regenerates the cache
- Theme or CSS changes may not appear correctly when old cached resources are reused, leading to mismatched icons, broken styling, or interface elements that look different from the selected theme
- Large accumulated cache folders waste disk space over time, especially with plugin web content and repeated updates, while clearing them only removes temporary files and not notes or attachments
- A damaged cache can trigger repeated reload behavior, sluggish workspace switching, or plugin views that never finish painting because Electron keeps reusing bad cached responses
- GPU acceleration issues often show up as visual glitches only in Obsidian, and clearing GPUCache is a common fix when the app becomes unstable after a system graphics update
