Will clearing Codex Desktop caches delete my conversations or signed-in session?

No. This cleaner targets disposable web, code, GPU, shader, component, extension-package, and dictionary caches only. Your conversations, browser profiles, logins, local storage, sessions, plugins, and runtimes are left in place.

Why does Codex Desktop use so much disk space in its cache folders?

Codex Desktop includes Chromium-based web content, compiled JavaScript bytecode, HTTP resources, and several GPU shader caches that accumulate over time. After updates and repeated use, old cache generations can remain on disk until they are manually cleaned.

Is it safe to delete Codex GPU and shader caches?

Yes. GPUCache, DawnGraphiteCache, DawnWebGPUCache, GrShaderCache, and ShaderCache are rebuildable performance caches, not user documents or settings. The first launch afterward may be a bit slower while Codex recompiles shaders and repopulates GPU data.

Why did Codex start flickering or showing blank areas after a graphics driver update?

Chromium and Electron often keep GPU and shader cache files that were generated for an older driver state. When those cached artifacts no longer match the current driver, Codex can show flicker, black panels, or failed hardware-accelerated rendering until the caches are cleared and regenerated.

Apps

Codex Desktop Caches

Codex Desktop stores several Chromium and Electron cache layers on Windows so its embedded web app can start quickly and render efficiently. These include HTTP disk cache data, V8 code cache, GPUCache entries, DawnGraphiteCache and DawnWebGPUCache shader artifacts, shared dictionary cache files, Chromium component and extension CRX package caches, and Skia shader caches such as GrShaderCache and ShaderCache. Kudu removes only those disposable caches so Codex can rebuild them cleanly, while preserving conversations, browser profiles, logins, local storage, sessions, plugins, and runtimes.

Why clean Codex Desktop Caches?

Corrupted HTTP cache entries can leave Codex showing outdated UI assets, broken styling, or pages that only start working again after a hard refresh or restart
Invalidated V8 code cache after a Codex or Chromium update can cause unusually slow first launch, delayed panel loading, or brief freezes while scripts are recompiled
GPUCache data tied to an older graphics driver can become invalid after a driver update, leading to black panes, flickering, or rendering glitches until the cache is rebuilt
Stale DawnGraphiteCache or DawnWebGPUCache shader artifacts can cause choppy animations, blank accelerated surfaces, or errors in hardware-accelerated views during startup
Damaged GrShaderCache or ShaderCache files can produce stutter the first time Codex draws complex interface elements, with scrolling or transitions hitching more than usual
Broken shared dictionary cache files can interfere with Chromium's compressed resource loading, which shows up as incomplete content, repeated re-downloads, or unexpectedly heavy network use
Old component_crx_cache and extensions_crx_cache packages can leave bundled browser components stuck on mismatched versions, causing features to fail to load until Codex fetches fresh packages
