VSCodium
Built on Electron and the same codebase as VS Code, VSCodium stores Chromium disk cache entries, V8 compiled bytecode in Code Cache and CachedData, GPU shader and raster data in GPUCache, downloaded extension .vsix packages, and rotating diagnostic logs to speed up the workbench, extension host, and webviews. When those caches go stale after an app, extension, or graphics driver update, users can see odd UI behavior, slow startup, or rendering glitches. Kudu removes only those disposable caches and logs, while preserving your settings, installed extensions, accounts, and workspace state.
Why clean VSCodium?
- Invalidated V8 bytecode after a VSCodium or extension update can make startup and window restore feel unusually slow until Code Cache and CachedData rebuild
- Stale Chromium Cache_Data entries can leave extension webviews showing old content, broken styling, or sign-in pages that never refresh correctly
- GPUCache data compiled against an older graphics driver can cause black editor areas, flickering panels, or laggy scrolling after a driver update
- CachedExtensionVSIXs can accumulate old extension installer packages, wasting hundreds of megabytes even though the extensions are already installed
- Oversized logs from repeated extension crashes or remote session failures can consume disk space and make it harder to spot current errors
- Corrupted disk cache records may cause blank Settings UI sections, missing icons, or command palette actions that open empty webviews
- Clearing disposable caches is a safe first step when VSCodium behaves inconsistently across launches, because it resets temporary Electron data without touching projects or user preferences
