Hearthglen
Built on Electron, Hearthglen stores several Chromium runtime caches under its Windows profile to speed up loading the app shell, card art, and GPU-rendered interface elements. Those files include HTTP disk cache entries in Cache_Data, V8 compiled script data in Code Cache, GPU pipeline and shader data in GPUCache, DawnGraphiteCache and DawnWebGPUCache, plus Shared Dictionary cache data used for compressed web content delivery. Kudu removes only these disposable caches so Hearthglen can rebuild fresh copies without affecting accounts, decks, settings, or other personal data.
Why clean Hearthglen?
- Stale HTTP cache entries in Cache_Data can keep serving outdated app assets after a Hearthglen update, which shows up as missing icons, broken layouts, or parts of the interface refusing to load correctly
- Invalidated V8 bytecode in Code Cache after an Electron or app update can make Hearthglen launch slowly or hang on a blank window the first time until scripts are recompiled
- Old GPUCache data tied to a previous graphics driver version can be rejected by Chromium, causing black panels, flickering animations, or a sluggish first redraw after updating your GPU driver
- Corrupted DawnGraphiteCache or DawnWebGPUCache shader and pipeline blobs can cause stutter during menu transitions, delayed card effects, or rendering glitches in hardware-accelerated scenes
- A damaged Shared Dictionary cache can break dictionary-based compression for downloaded web assets, leading to incomplete text, mismatched UI fragments, or repeated re-downloading of the same resources
- Oversized browser caches inside Hearthglen can waste hundreds of megabytes on old art, scripts, and compressed assets, especially after frequent patches, while clearing them frees space without touching saved data
