  "message": "[Impeller] remove Vulkan pipeline cache mutex. (#43085)\n\nAt least from what I\u0027ve found online, this API is already safe to call from multiple threads. From testing, at startup the presence of the mutex is adding ~100ms to shader creation time, as all compilations across N threads are fighting for the same lock.\r\n\r\nhttps://github.com/flutter/flutter/issues/129050",
