I attach here PHD2 logs of the photo from the first post.
Here is a capture of the Synscan app showing the firmware version. It is 3.22.A5.
I think I can downgrade it to v3.20 to test it, but... I don't have the problem in windows. Is so frustrating . It seems like the bug only affects in linux. Ascom driver is from Skywatcher. Perhaps they solved or ignore the bug in their driver, don't you think so?
