I tested version 4 of the patch series on a custom design and I saw also the jumps as described by Richard. I played a little with the sample delay and it got better but I couldn't completely remove the jumps. The other issue I had with version 3, the pen_ups during the busy loop, is solved. I experienced some pen_up misses during the busy loop if I used a too high sample delay, without the sample delay it was ok.
