Browsers
Opera
Built on Chromium, Opera stores website resources in its HTTP disk cache along with GPUCache files, Code Cache bytecode, service worker data, media cache entries, and SQLite-backed browser databases under its profile folder. These files speed up page loads, video playback, extensions, and site rendering, but they can become stale after browser updates, graphics driver changes, or broken site data. Kudu removes Opera's disposable cache layers and tidies cache-related database files without touching bookmarks, saved passwords, extensions, accounts, or browsing settings.
Why clean Opera?
- Corrupted HTTP cache entries can make sites load with missing CSS or outdated JavaScript, so pages look broken, buttons stop responding, or logins loop until fresh files are downloaded
- Invalidated V8 Code Cache after an Opera or Chromium engine update often causes a noticeably slow first launch of web apps and extensions while bytecode is rebuilt
- Stale GPUCache data after a graphics driver update can trigger black rectangles, flickering video, or blank page areas because old shader and rendering cache data no longer matches the driver
- Oversized media and image cache files waste gigabytes in the profile folder and show up as unexpectedly high disk usage even though personal data like bookmarks and passwords are unchanged
- Bad service worker cache state can leave sites stuck on an old offline version, causing pages to ignore recent changes or repeatedly serve outdated content until the cache is cleared
- SQLite cache databases accumulate free pages and fragmentation over time; VACUUM rewrites the database into a compact file without deleting rows, which can reduce profile bloat and fix sluggish cache access
- Damaged cached session resources can cause tabs to reload more often, thumbnails to appear blank, or embedded audio and video to stall until Opera rebuilds the temporary data
