Codex Desktop Partition Caches
Inside Codex Desktop, the controlled browser partitions under the embedded Chromium runtime keep per-partition HTTP disk cache entries, Network persistent state, Code Cache bytecode, and GPUCache shader and raster data for isolated web surfaces. Those files exist to speed up reloads of embedded pages and authenticated resources, but they can become stale after app updates, server-side asset changes, or graphics driver changes. Kudu clears only these partition cache files so Codex can rebuild fresh copies, while leaving extensions, history, downloads, logins, sessions, Local Storage, service-worker data, offline content, and other user data untouched.
Why clean Codex Desktop Partition Caches?
- Stale HTTP disk cache entries can keep an older JavaScript bundle or stylesheet pinned, which shows up as missing buttons, broken layouts, or a Codex panel that never finishes loading until the cache is rebuilt
- Invalidated Chromium Code Cache bytecode after a Codex Desktop update can cause one partitioned web view to launch slowly or render a blank area on first open while fresh V8 cache files are generated
- GPUCache data compiled against a previous graphics driver version can become unusable after a driver update, leading to black panels, flicker, or jerky scrolling in Codex's embedded browser surfaces
- Corrupted per-partition network cache records can cause repeated reload loops, sign-in prompts that appear inconsistent, or resources that fail with partial page rendering even though the network connection is fine
- Large accumulated cache objects across multiple isolated partitions can consume hundreds of megabytes under the app package cache path, which users notice as unexpectedly high Codex disk usage on Windows
- Outdated cached API responses or static assets in one controlled-browser partition can make only part of the app behave incorrectly, such as one view showing old content while another has already updated
