Logitech G HUB
Built on Electron, Logitech G HUB keeps several Chromium-style caches on disk, including HTTP Cache_Data entries for downloaded UI assets and device content, V8 Code Cache bytecode for its JavaScript interface, GPUCache shader and rendering data, and content-addressed package files under ProgramData used to stage updates and components. When those caches go stale or grow excessively, G HUB can show a blank or partially rendered interface, slow startup, or repeated redownloads; Kudu removes only these disposable cache files while leaving device profiles, macros, account sign-in, and settings untouched.
Why clean Logitech G HUB?
- Corrupted Cache_Data entries can make G HUB load a blank window, missing device images, or panels that never finish populating because the Electron UI is reading bad cached web assets
- Invalidated V8 Code Cache after a G HUB update can cause a noticeably slow first launch, long delays opening the home screen, or a temporarily unresponsive interface until bytecode is rebuilt
- Stale GPUCache data after a graphics driver update can break Chromium's cached shader pipeline, leading to black panes, flickering animations, or choppy scrolling in the app
- ProgramData package cache files can accumulate across updates and hardware content downloads, wasting disk space and sometimes causing repeated repair or redownload behavior when old package fragments are reused
- A damaged Chromium disk cache can keep serving outdated frontend resources, which shows up as buttons that do nothing, pages that render incorrectly, or settings views that fail to refresh after an update
- Large cache folders increase the amount of small-file scanning Windows and antivirus tools must do, which users notice as slower G HUB launches and extra disk activity when the app starts
- Downloaded package and asset caches are disposable, so clearing them is a practical reset when G HUB gets stuck on loading screens or keeps reopening to the same broken UI state without affecting profiles or macros
