GOG Galaxy
GOG Galaxy stores Chromium-based web cache data for its interface and integrations, including HTTP disk cache entries, GPU shader cache files, cookies, code cache, and other browser storage used to render the client, store downloaded web assets, and speed up embedded pages. It also writes service and client log files under ProgramData for background platform integrations and update activity; Kudu removes these disposable webcache and log files while leaving installed games, cloud saves, account sign-in data, and launcher settings untouched.
Why clean GOG Galaxy?
- Stale Chromium disk cache entries can leave the Store, Library, or Friends views partially blank or stuck loading because Galaxy keeps reusing outdated web assets
- GPU cache files built against an older graphics driver can be invalid after a driver update, causing black panels, flickering interface elements, or sluggish rendering until the cache is rebuilt
- Corrupted code cache data for Galaxy's embedded web UI can make the client start slowly, freeze on launch, or need multiple restarts before pages render correctly
- Overgrown webcache folders can consume hundreds of megabytes with old images, scripts, and response bodies, which shows up as unexpectedly high disk usage in AppData or ProgramData
- Accumulated service logs from sync errors, integration retries, and update checks can grow continuously in ProgramData, especially if a linked platform keeps failing to connect, leading to large log folders and repeated background disk activity
- Cached login and session web data can become inconsistent after client updates or connection problems, which may show up as endless loading spinners, missing avatars, or integration panels that never finish refreshing
