Upscayl
Built on Electron, Upscayl stores Chromium HTTP cache data, V8 compiled code in Code Cache, GPU pipeline and shader data in GPUCache and DawnCache, plus rolling log files under its profile in AppData. These files help its interface load faster and let WebGPU or GPU-accelerated rendering avoid recompiling work every launch, but they can become stale after app, Chromium, or graphics driver changes. Kudu removes those temporary caches and settled logs while leaving your images, models, app settings, and project data alone.
Why clean Upscayl?
- Invalidated V8 bytecode after an Upscayl update can make the window open slowly or briefly show a blank interface until the Code Cache rebuilds
- Stale GPUCache entries from a previous graphics driver version can trigger black panels, flickering previews, or a sluggish first render when the app starts
- Outdated DawnCache shader and pipeline blobs can conflict with WebGPU changes, causing startup hangs, device initialization errors, or repeated recompilation pauses
- Corrupted Chromium Cache_Data files can leave parts of the Electron UI missing, with icons, bundled assets, or screens not loading correctly until the cache is cleared
- Accumulated log files grow quietly over time after repeated upscaling sessions and error retries, wasting disk space and making real troubleshooting harder because old noise buries current issues
- A cache built against older bundled web assets can make Upscayl feel inconsistent after an update, with delayed controls or rendering glitches that disappear once fresh cache files are generated
