Codex Desktop Partition Caches
Codex Desktop keeps Chromium-style partition caches under its internal controlled-browser profile for embedded web surfaces that are isolated from the main app state. Those partitions accumulate HTTP disk cache entries, compiled script resources, GPU shader and Skia caches, media cache files, and code cache data so repeated views load faster and render smoothly. Kudu removes only these partition cache files from Codex Desktop on Windows, leaving extensions, browsing history, downloads, logins, sessions, local storage, service-worker data, offline content, and other user data intact.
Why clean Codex Desktop Partition Caches?
- Stale HTTP cache entries inside a partition can keep serving an older JavaScript bundle or stylesheet after Codex updates, which shows up as broken panels, missing buttons, or a view that never finishes loading until the cache is rebuilt.
- Invalidated GPUCache data after a graphics driver update can leave Chromium reusing obsolete shader artifacts, causing black panes, flickering, or jerky scrolling in embedded Codex web views.
- Corrupted Code Cache bytecode for partitioned web content can make the first open of a workspace or tool hang or crash, then behave normally only after those compiled scripts are regenerated.
- Oversized media and image cache files in isolated partitions can consume hundreds of megabytes over time, and users usually notice this as unexpectedly high AppData disk usage even though their actual Codex content has not grown.
- A bad cached redirect, cookie-adjacent network artifact, or expired API response in a partition can trap a specific embedded page in a sign-in loop or repeated error state while the rest of Codex still works.
- Skia and raster cache corruption can cause blank icons, missing thumbnails, or text that paints incorrectly in one Codex surface until the renderer recreates fresh cache data.
- Partition cache indexes can become internally inconsistent after an interrupted update or forced shutdown, which often appears as one embedded browser area loading much slower than others or repeatedly re-downloading the same assets.
