Same software version I have here, too. Aug 2 it went away (at least I didn't notice it) however I may not have been paying attention to it right at that particular time.When I transitioned from my 722Ks to the Hoppers I immediately noticed that it glitches at the top (and sometimes bottom) of each hour. It's very brief but annoying. I've been patiently waiting for them to fix it. I do still have a 722K on a separate account, it has L752, haven't noticed any top/bottom of hour glitches yet, but I suspect that L752 is what introduced the glitch for others. Definitely not a step in the right direction...
