Polyscope
Built on Electron, Polyscope writes several Chromium runtime caches under its Windows profile, including HTTP disk cache entries in Cache_Data, V8 Code Cache bytecode, GPUCache data, DawnGraphiteCache and DawnWebGPUCache shader and pipeline blobs, Shared Dictionary compression cache files, and settled application logs. These files exist to speed up UI loading, reuse downloaded web assets, and avoid recompiling rendering pipelines, but they can become stale after app or graphics driver changes. Kudu removes only those disposable caches and logs while leaving local storage, network state, sessions, settings, and account data intact.
Why clean Polyscope?
- Corrupted HTTP cache entries in Cache_Data can make parts of the Polyscope interface load with missing styling, blank panels, or outdated bundled assets until the cache is rebuilt
- Invalidated V8 bytecode in Code Cache after a Polyscope update can cause a noticeably slow first launch, repeated script recompilation, or renderer crashes during startup
- Stale GPUCache data from a previous graphics driver version can lead to black windows, flickering controls, or sluggish redraws when Polyscope uses hardware acceleration
- Outdated DawnGraphiteCache and DawnWebGPUCache pipeline blobs can cause stutter, delayed canvas rendering, or visual glitches after a GPU driver update or Electron runtime change
- A bad Shared Dictionary cache can break Chromium's cached compression state, showing incomplete responses, endlessly spinning views, or assets that never finish loading
- Settled logs can grow over time and waste disk space, especially after repeated startup failures or renderer errors, leaving the app folder much larger than expected
