Slack
Slack’s desktop app stores Chromium network disk cache entries, Electron V8 compiled code in the Code Cache, GPU raster and shader data in GPUCache, and rotating diagnostic logs so workspaces, channels, images, and the interface load faster between sessions. Those files can become stale after Slack, Chromium, or graphics driver updates, leading to broken media, rendering glitches, or unusually large disk usage. Kudu removes only Slack’s disposable cache and log files, leaving messages, downloads, signed-in workspaces, settings, and account data untouched.
Why clean Slack?
- Stale Chromium disk cache entries can make avatars, emoji, or shared images fail to load correctly, so Slack shows blank placeholders or endlessly spinning media previews
- Invalidated Electron V8 compiled code after a Slack update can slow the next launch and leave the app feeling stuck on startup while the code cache rebuilds
- Old GPUCache data from a previous graphics driver version can cause rendering corruption, black panels, or flickering until Slack regenerates its GPU shader and raster cache
- A bloated Cache_Data folder keeps old workspace assets and attachment responses on disk, which shows up as Slack using far more storage than expected
- Corrupted cached web resources can leave channel sidebars, message panes, or sign-in screens partially unstyled, missing elements, or repeatedly reloading
- Accumulated Slack logs grow quietly in the background after crashes or connection trouble, wasting disk space while preserving no messages or files you actually need
