Just figured I would mention that I ran both 22.214.171.124 and the latest PhD2 build and GNS beta last night and it was completely flawless with only the “not dithering after first frame” as an issue. That was solved with a dummy 30 second first exposure. Looking great and very stable on Windows 10 Pro.
