Catsxp
Built on Chromium, CatsXP stores a large set of browser-generated data under its profile, including HTTP disk cache entries, GPUCache files, Code Cache bytecode for JavaScript and WebUI resources, media caches, and service worker script caches created to speed up page loads, video playback, and web app startup. When those temporary files become stale or oversized, CatsXP can keep using invalid network responses, outdated V8 compiled code, or invalidated GPU shader data; Kudu removes those cache directories while leaving bookmarks, saved passwords, cookies you still use for sign-in, history, extensions, and other personal profile data untouched.
Why clean Catsxp?
- Corrupted HTTP cache entries can make sites load with missing CSS or broken images, so pages look unstyled or partially blank until the cache is rebuilt
- Stale service worker and script cache data can keep an older version of a web app around, causing pages to ignore recent site updates or loop on loading screens
- Invalidated V8 Code Cache after a CatsXP or Chromium engine update can cause sluggish first loads, renderer hiccups, or tabs that briefly freeze while JavaScript recompiles
- GPUCache data tied to a previous graphics driver version can become invalid after a driver update, leading to black rectangles, flickering video, or stuttering during canvas and WebGL rendering
- An oversized media and disk cache can consume several gigabytes in the profile folder, leaving users with unexpectedly low free space even though no personal files were added
- Damaged cached responses can trigger repeated refresh behavior, login pages that never finish rendering, or tabs that show old content until cache files are cleared
- If CatsXP stores site data in SQLite-backed internal databases, page fragmentation can accumulate over time; VACUUM rewrites the database file to compact free pages without deleting your saved rows
