    const std::string& layout_name) {

      return true;
    }
  }

      {base::MayBlock(), base::TaskShutdownBehavior::CONTINUE_ON_SHUTDOWN},
      base::Bind(&LoadKeymap, layout_name, base::ThreadTaskRunnerHandle::Get(),
                 reply_callback));
#else

}

2. ui/gl/gl_context.cc

#if DCHECK_IS_ON()
    GLenum error = glGetError();
    // Accepting a context loss error here enables using debug mode to work on
    // context loss handling in virtual context mode.
    // There should be no other errors from the previous context leaking into
    // the new context.
-    DCHECK(error == GL_NO_ERROR || error == GL_CONTEXT_LOST_KHR) <<
-        "GL error was: " << error;
+    if (error != GL_NO_ERROR) {
+            LOG(ERROR) << error << "\n";
