Hearthglen
Built on Electron, Hearthglen stores several Chromium runtime caches under its profile on Windows so the app can reopen faster and avoid recompiling the same web assets every session. These include HTTP disk cache files in Cache_Data, V8 compiled script data in Code Cache, GPU pipeline and command caches in GPUCache, DawnGraphiteCache and DawnWebGPUCache, plus Shared Dictionary cache entries used to decode compressed network responses. Kudu removes only those disposable caches when they become oversized or stale, without touching Hearthglen accounts, saved data, settings, or passwords.
Why clean Hearthglen?
- Stale HTTP cache entries in Cache_Data can keep serving old JavaScript or CSS after a Hearthglen update, showing a broken interface, missing panels, or buttons that stop responding until fresh assets are downloaded
- Invalidated V8 bytecode in Code Cache after an Electron or app update often causes one unusually slow launch, repeated renderer restarts, or pages that stay blank while scripts are recompiled
- Old GPUCache data left behind after a graphics driver update can mismatch Chromium's GPU pipeline state, leading to black windows, flickering, or choppy animations until the cache is rebuilt
- Corrupted DawnGraphiteCache or DawnWebGPUCache shader and pipeline blobs can cause stutter during scene transitions, delayed rendering, or UI elements that appear only after resizing the window
- An oversized Shared Dictionary cache can make Hearthglen keep outdated compression dictionaries for network responses, which may show partial page loads, garbled content, or repeated redownloads of the same resources
- When these Electron caches grow unchecked, Hearthglen may consume hundreds of megabytes of profile space and feel slower to start because Chromium has to scan and validate more cached entries before rendering
