It is not universal - I don't have it.
I use the GearMin watchface and also notice a definite lag since the 9.2 update last night. I used to have the 3HR and it had a lag too. When I upgraded to the 5x a month ago I was happy to not have any lag. Now it's back. I'm going to try uninstalling and reinstalling, and also try some of the other multi-data watch faces.
I have already tried a few other multi data custom watch faces, Data Lover, My Watch, ALDigital and also the Garmin Sport Master, they all introduce a major lag when switching.
Subtleguru - Which watch face are you using ?
