Logitech G HUB
Logitech G HUB stores several layers of temporary data on Windows, including Chromium HTTP disk cache entries in Cache_Data, Electron V8 code cache in Code Cache, GPU shader and render artifacts in GPUCache, and downloaded content-addressed packages under ProgramData for app components and updates. These files speed up the app's web-based interface, device module loading, and graphics rendering, but they can become stale after G HUB updates, driver changes, or interrupted downloads. Kudu removes only these rebuildable caches while leaving profiles, macros, device assignments, account data, and settings untouched, and it preserves files used in the last week.
Why clean Logitech G HUB?
- Invalidated Electron V8 bytecode after a G HUB update can make the window open slowly or sit on a blank loading screen until fresh code cache is rebuilt
- Stale Chromium HTTP cache entries can keep serving outdated UI assets, leading to missing panels, broken buttons, or pages that never finish loading inside G HUB
- Old GPUCache shader data from a graphics driver update can cause black or flickering interface elements, especially in animated device previews and transitions
- Corrupted content-addressed package downloads in ProgramData can leave G HUB stuck retrying updates or repeatedly reinstalling device components without finishing
- An oversized Cache_Data folder can consume hundreds of megabytes and make G HUB feel sluggish when browsing device pages because the embedded browser has to manage too many stale entries
- Partial downloads after a crash or forced shutdown can cause missing icons, empty integration pages, or devices that appear without their full configuration screens until the cache is refreshed
