Modern MTR
Modern MTR stores several Chromium and Electron runtime caches under your Windows profile so its web-based interface can start faster and redraw network graphs smoothly. Those folders typically contain HTTP disk cache entries in Cache_Data, V8 compiled JavaScript bytecode in Code Cache, and GPU shader and render pipeline data in GPUCache; Kudu removes these transient files when they become oversized, outdated, or corrupted. Your saved hosts, probe settings, history, accounts, and other personal configuration are left alone.
Why clean Modern MTR?
- Corrupted HTTP cache entries in Cache_Data can make the Modern MTR interface load with missing styles, broken icons, or panels that never finish rendering.
- Invalidated V8 bytecode in Code Cache after a Modern MTR update can cause a noticeably slow first launch, white windows, or repeated UI rebuilds until the cache is regenerated.
- Stale GPUCache data after a graphics driver update can leave Chromium using invalid shader blobs, which shows up as flickering charts, black graph areas, or stuttering during redraws.
- An oversized disk cache can waste hundreds of megabytes on old web assets and force longer startup scans before the app reaches the traceroute view.
- Partially written cache files after a crash or forced shutdown can cause Modern MTR to reopen with a blank window, unresponsive controls, or repeated loading spinners.
- Old cached frontend assets can conflict with newer bundled code, leading to mismatched interface behavior such as buttons that stop responding or route tables that fail to refresh.
