blue essence flicker and sound on login

whenever i log in my blue essence flickers and there a sound that gets played. is this some kind of bug? or is the some other feature that i dont know about? either way its annoying and confusing and id like it to stop. or at the very least understand just what is happening so i can direct my annoyance over it at a specific thing and not just another vaguely unexplained aspect of league and its client.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
