In chatting with Marco we discovered we had the same issue, namely after a sub is downloaded, SGP gives dither command but starts the new image capture immediately, I have a setting that stops current frame if guidestar distance is to far so in most cases it will interrupt the sub. This repeats 2 - 3 times, and then SGP finally realises it needs to wait for the dither ...
We use both D810A ... Now I can't remember seeing this with CCD camera, but I could be wrong ...
Using PHD 2.6.1 and SGP 2.5.1.17 (Marco is running PHD 2.6.2 I think)
(forget log after midnight, something went wrong, never had this, W10 also updated ...)
