Game lags when I use Smart Ping wheel for the first time in a match

Pretty much Title:

When i make a smart ping like "on my way" for the first time in the match my game lags for 2-3 Seconds. It's not game changing but it's annoying.

Especially when you forget to do it in the very beginning of the match and then do it in the middle of a gank.

Am I the only one who have this problem?

This happens to me since 9.20 or so.
