Modern MTR
Built on Electron, Modern MTR stores Chromium disk cache entries, V8 compiled script data in Code Cache, and GPUCache shader and rendering blobs to speed up loading its traceroute interface and embedded web assets. Those files accumulate as the app updates and as Windows graphics drivers change, leaving behind stale HTTP cache objects, invalidated bytecode, and obsolete GPU pipeline data. Kudu removes Modern MTR's Cache_Data, Code Cache, and GPUCache folders without touching saved hosts, probe settings, accounts, or other user data.
Why clean Modern MTR?
- Stale Chromium disk cache objects can leave parts of the Modern MTR interface loading incorrectly, with blank panes, missing styles, or controls that do not respond until assets are fetched again
- Invalidated V8 bytecode after a Modern MTR update forces Electron to ignore old compiled scripts, which often shows up as a noticeably slow first launch while the Code Cache rebuilds
- Corrupted Cache_Data entries can make the app repeatedly reuse bad web resources, causing endless loading spinners or panels that never fully render even after restarting
- GPUCache blobs generated before a Windows graphics driver update may no longer match the current driver, leading to flickering, black regions, or stutter when the interface redraws
- Overgrown Chromium cache folders waste space in Roaming AppData and can make profile backups larger, especially on systems where Modern MTR is opened often for network diagnostics
- A damaged GPU cache can trigger rendering fallbacks in Electron, which users notice as sluggish scrolling, delayed chart redraws, or temporary visual glitches in the window
