This is not new in v278, but seems to be becoming more and more common over time. I really do not know what is causing it yet.
A couple of people have noticed this on players WITHOUT Hijack installed, though it is much more common with Hijack. Looks like a race condition in the hardware init, or possibly a hardware resource contention issue in the drivers somewhere.
Hijack v280 includes some new safeguards to try and reduce hardware contention in a couple of cases, which might improve it some.
