Some additional information: I'm not on the beta, my iPad is running 14.6. Also, Insufficient memory is the most common error I see, but other times it'll be a [CAMetalLayer setInputTime:] - non-zero time already exists!. Either way, they happen dozens of times every pencil stroke once it's reached its limits. The total ram usage of the app is anywhere between 150-500 MB when this happens. Looking for memory leaks, it seems that Instruments identifies instantiating a PKCanvasView as the source of a leak.
