Yes, more or less. As I look at it now, I wonder if the master really did a clear, or if the slaves simply drew background polygons over their respective regions. It's also possible that the swap guarantees a flush for commands queued by all the slaves, but I'm unsure of that without checking the spec. | This is fairly sensible and clearly requires a shared buffer.
