Pinokio Performance Caches
Pinokio stores several Chromium and Electron performance caches under its profile on Windows to speed up startup and rendering. These include V8 compiled code in the Code Cache, GPU process data in GPUCache, and Dawn WebGPU or Graphite shader and pipeline blobs in DawnGraphiteCache and DawnWebGPUCache, all created so the app can avoid recompiling scripts and graphics resources every launch. Kudu removes only these rebuildable performance caches, preserving Pinokio application data, accounts, settings, and downloaded project files.
Why clean Pinokio Performance Caches?
- Invalidated V8 bytecode in Pinokio's Code Cache after an app update can make the first launch hang on a blank or partially drawn window until scripts are recompiled
- GPUCache entries from an older graphics driver can conflict with the current one, causing black panels, flickering, or sluggish redraws until the cache is rebuilt
- Stale DawnWebGPUCache pipeline data can trigger rendering glitches or failed hardware-accelerated views when Pinokio's embedded Chromium changes its WebGPU behavior
- Corrupted DawnGraphiteCache shader blobs can lead to UI artifacts such as missing icons, broken gradients, or delayed rendering in GPU-accelerated surfaces
- Oversized performance caches waste disk space in the Roaming profile, which users often notice as Pinokio consuming far more AppData storage than expected
- After repeated app and driver updates, mixed old and new cache entries can increase startup work instead of reducing it, showing up as longer launches before the interface becomes responsive
