Flying this afternoon with v12 SW I selected direct to and the magenta line was displaced from the current location by a mile or more. I tried several times with the same result. Later < 10 minutes it was back to working as expected. The first thought was lack of sat orientation but I then thought the end of the magenta line still would be at the same point as the aircraft symbol but possibly inaccurate! Any ideas? I never saw this with V11 or earlier.
