Hyper Terminal
Built on Electron and Chromium, Hyper stores several browser-style caches to speed up rendering its interface and terminal tabs, including HTTP disk cache entries in Cache_Data, V8 code cache files in Code Cache, and GPU raster or shader data in GPUCache. These files help Hyper load its React-based UI, extensions, fonts, and accelerated rendering paths faster, but they can become stale after app or graphics driver changes. Kudu removes only those temporary cache files so Hyper can rebuild them cleanly without touching profiles, shell history, sessions, accounts, or preferences.
Why clean Hyper Terminal?
- Stale HTTP disk cache entries in Cache_Data can leave Hyper loading old UI assets after an update, which shows up as missing interface elements, broken styling, or a window that opens incorrectly
- Invalidated V8 bytecode in Hyper's Code Cache after an Electron upgrade can make the first launch unusually slow or cause repeated pauses while the app recompiles JavaScript for the interface
- Outdated GPUCache data after a graphics driver update can conflict with Chromium's accelerated rendering path, causing black windows, flickering text, or a blank terminal area until the cache is rebuilt
- Corrupted cache files can make Hyper hang on startup or display an unresponsive frame even though the underlying shell process is fine, because the Electron front end fails before drawing properly
- Oversized accumulated cache data from themes, extension assets, and remote content can waste hundreds of megabytes over time, which users notice as Hyper taking more disk space than expected
- Bad cached font or rendering resources can cause blurry glyphs, missing icon fonts, or terminal text that draws incorrectly until Hyper fetches and compiles fresh assets
- Removing these caches is low risk because they are regenerated automatically; it fixes temporary Electron rendering problems without deleting tabs configuration, plugins, shell history, or saved settings
