Hi Jesse, developer on Vision here. I looked into in and the time sync issue is definitely a bug on our end. One thing that may work until we get it fixed is to use 25 or 50 fps. The issue seems to be related to the number of milliseconds per frame not being evenly divisible in most of the frame rates. 25 and 50 do not have that problem, so they may work out better for you until we can get the fix into a release.
