+The Minecraft startup fixture uses `tools/trace_replay/fixtures/minecraft-1.21.4-startup.tgz`, golden image
+`minecraft-1.21.4-startup.0000092195.png`, `--target-call 92195`, `--width 854`, and `--height 480`.
+
 The Linux runner loads MobileGL by path with `dlopen`. It uses an EGL pbuffer for `DirectGLES` and maps the pbuffer
 path to `VK_EXT_headless_surface` for `DirectVulkan`, so CI does not need an X11 or Wayland window.
