Modern MTR
Built on Electron, Modern MTR stores Chromium disk cache entries for its web interface, V8 code cache files for precompiled JavaScript, and GPUCache data such as shader and rendering state blobs used to accelerate the app. These caches help the route-tracing UI load faster and render smoothly, but they can become stale after app or graphics driver changes; Kudu removes the cached web content, compiled code cache, and GPU cache without touching saved hosts, settings, or account data.
Why clean Modern MTR?
- Outdated Chromium disk cache entries can leave parts of the Modern MTR interface stuck showing old assets, with buttons, graphs, or panes failing to refresh correctly after an update
- Invalidated V8 bytecode in the Code Cache after a Modern MTR upgrade can cause an unusually slow first launch, repeated renderer starts, or a white window before the UI rebuilds its compiled scripts
- Corrupted Cache_Data files can make the app load incomplete frontend resources, which shows up as missing styling, blank sections, or controls that stop responding
- Stale GPUCache blobs from a previous graphics driver version can cause rendering glitches, flickering charts, or black and blank surfaces until Chromium regenerates the cache
- A bloated web cache can waste hundreds of megabytes on old interface assets and network responses, increasing profile size and making troubleshooting profile-related startup issues harder
- Bad cached frontend data can keep Modern MTR using mismatched JavaScript and asset versions, leading to broken route tables, misdrawn latency graphs, or inconsistent behavior between launches
