Opera GX
Opera GX stores Chromium-style browsing data in its profile, including HTTP disk cache entries, GPU shader and media caches, favicon and thumbnail databases, and SQLite databases such as History, Favicons, Top Sites, and Cookies with associated WAL and journal files. These files speed up page loads, restore site icons and previews, and preserve session state, but they can also grow large or become stale after browser updates, site changes, or graphics driver changes. Kudu removes disposable cache files and compacts the relevant SQLite databases, including cleaning up WAL growth and page fragmentation, without touching saved passwords, synced accounts, bookmarks, or browser settings.
Why clean Opera GX?
- Stale Chromium disk cache entries can serve outdated site assets, showing broken layouts, missing images, or pages that only load correctly after a hard refresh
- Invalid GPU cache and shader data after a graphics driver update can cause black page flashes, flickering video, or sluggish scrolling until Opera GX rebuilds the cache
- Corrupted media cache files can lead to videos that buffer forever, restart unexpectedly, or play audio with a blank picture on streaming sites
- Oversized favicon and thumbnail databases can leave Speed Dial tiles blank or slow to populate, especially after many visited sites have changed icons
- History, Favicons, and Top Sites SQLite files accumulate free pages over time; VACUUM rewrites the database to remove page fragmentation without deleting rows, reducing profile bloat and improving responsiveness
- Large WAL and journal files left behind by frequent writes can consume hundreds of megabytes and make startup or shutdown feel unusually slow while Opera processes profile data
Cache paths Kudu targets
These databases are vacuumed (compacted) — no data is deleted. SQLite VACUUM reclaims wasted space left over from normal usage.
