Not explicitly, but as both audio and video don't block, they are in sync.

Unless I am misunderstanding what you're saying, you are mixing frame
rendering and queuing. The blog post I linked is about the latter.
Nageru treats frames as atomic when queuing and thus has no issues
with tearing, queuing is about stuttering.
This does bring up an interesting point, though: Is there something to
read up upon voctomix' queuing? I didn't dig into that when LCA had
their issues, but I suspect that that's related.
