Polyscope
Built on Electron, Polyscope stores several Chromium runtime caches on Windows to speed up rendering and network-heavy UI work, including HTTP disk cache entries in Cache_Data, V8 code cache files, GPUCache data, DawnGraphiteCache and DawnWebGPUCache shader and pipeline artifacts, and Shared Dictionary compression cache files. It also accumulates settled application logs under its logs folder as the app records startup, renderer, and update events. Kudu removes those disposable caches and old logs while leaving local storage, network state, sessions, settings, accounts, and other user data untouched.
Why clean Polyscope?
- Invalidated V8 code cache after a Polyscope update can make the first launch unusually slow or leave parts of the interface loading later than expected until bytecode is rebuilt
- Stale GPUCache entries after a graphics driver update can cause black panels, flickering views, or sluggish redraws because Chromium has to discard incompatible shader data
- Outdated DawnGraphiteCache and DawnWebGPUCache artifacts can trigger rendering glitches, missing surfaces, or stutter when Polyscope uses newer GPU paths than the cached pipelines were built for
- A bloated Cache_Data folder keeps old HTTP responses and media fragments around, which can show up as unexpectedly large AppData usage and occasional loading oddities after backend changes
- Corrupted Shared Dictionary cache files can interfere with dictionary-compressed responses, leading to partial UI loads, repeated retries, or screens that look stuck until assets are fetched cleanly again
- Settled logs can quietly grow over time from repeated launches and renderer events, wasting disk space even though they no longer help day-to-day use
- Cleaning these runtime caches forces Polyscope to regenerate fresh browser-engine artifacts, which often resolves odd startup and rendering behavior without affecting sessions or saved work
