Default Lag on notification bar

I just updated to the new 4.4.2 in my Xperia Z, and immediately after I started using it I noticed quite a bad lag (Maybe a few fps) when the notification bar was swiped down. Switching to the quick tools is smooth, runs normally but as soon as you move the bar up or down it's very laggy.

Firmware: exzistenz 1.5.0 based on latest compilation

*

Is this related to my phone's hardware (RAM, CPU, ROM etc etc)

Or is it a software issue (Incorrectly installed firmware, firmware bug)

*

Thanks for answers*

If this is a new bug please help report it. Thanks!
