Having same issues... Playing on a Wired PC, Not only Meter erratic but the whole screen of the game client, Everything seems to be moving in installments, Not at all smooth.
Started Yesterday and I had a World Cup game last night, Totally lucky that I managed to time the ding.
I have run every clean I can think of, Also tried 3 different browsers.. Cloud, IE & Firefox but getting same result, Nothing at all smooth.. Almost to the point of unplayable Today.
Anybody with ideas ? Much appreciated folks..
