Apps
Hyper Terminal
Built on Electron and Chromium, Hyper stores several browser-style caches on disk to speed up rendering its interface and loading remote assets used by the app and extensions. These include HTTP disk cache entries in Cache_Data, V8 code cache files for JavaScript startup, and GPUCache data such as shader and render pipeline blobs; Kudu removes those temporary files when they become oversized, corrupted, or invalid after app and driver changes, without touching profiles, shell history, settings, or accounts.
Why clean Hyper Terminal?
- Invalidated V8 code cache after a Hyper or extension update can make the first launch hang on a blank or half-drawn window until the JavaScript bundles are recompiled
- Corrupted Cache_Data entries can leave the preferences UI, plugin assets, or embedded web content loading incompletely, with missing icons, broken panes, or repeated reload behavior
- Stale GPUCache blobs from a graphics driver update can cause black windows, flickering text, or rendering glitches when Hyper opens or when tabs redraw
- An oversized Chromium disk cache wastes space under the Hyper profile and can make startup slower as Electron scans and replaces old cache entries
- Bad cached extension resources can keep a theme or plugin stuck on an older version, so users see mismatched styling, missing fonts, or UI elements that do not respond correctly
- If Hyper crashes during a write, partial cache records may trigger repeated slow launches or visual corruption until the cache is rebuilt cleanly
- Cleaning only these caches resets temporary renderer data while leaving terminal sessions, shell configuration, saved preferences, and login details untouched
