Always synchronize terminal before rendering it

Previously, we were trying not to synchronize the terminal too often
because there could be multiple layout/paint calls prior to rendering
a frame.

Now that we perform a single render pass per frame, we can just synchronize
the terminal state. Not doing so could make it seem like we're dropping frames.
