Remove DispSync offsets

As it stands right now, all these offsets are doing are giving ~14ms
of CPU time to the application instead of 16.6ms, and based on some
systraces, we could use as much app time as possible. As such, it's
probably worth taking the minor theoretical latency hit and instead
using the time to reduce jank.
