Logitech G HUB
Logitech G HUB relies on an Electron-based interface, which creates Chromium disk cache files, V8 Code Cache bytecode, and GPUCache shader data to speed up loading its device views, animations, and web-driven UI panels. It also stores downloaded content-addressed packages under ProgramData for app components and assets used by lighting effects and device modules. Kudu removes stale browser-style cache data and old downloaded package cache entries while leaving profiles, macros, device assignments, account sign-in, and settings untouched.
Why clean Logitech G HUB?
- Outdated V8 Code Cache after a G HUB update can make the app open to a blank or half-rendered window on first launch until the bytecode is rebuilt
- A corrupted Chromium Cache_Data store can leave the home screen spinning, device tiles missing, or settings pages failing to populate even though your devices are connected
- GPUCache entries compiled against an older graphics driver can become invalid after a driver update, causing flicker, black panels, or stutter in G HUB's animated interface until the shader cache is regenerated
- Downloaded content-addressed packages in ProgramData can accumulate across module and asset updates, wasting disk space with old package versions that G HUB no longer needs
- Stale cached web assets can keep showing outdated prompts, broken banners, or incomplete integrations after G HUB updates because the UI is loading old local resources first
- When the Electron cache grows too large, G HUB may launch slowly, redraw sluggishly while switching between devices, or take longer to load lighting and assignment pages
- Cleaning old package cache and browser cache keeps only recently used content, which helps resolve repeated UI glitches without deleting onboard profiles, macros, or account data
