Thank you for giving that a go for me @Volkmar_Sitte , the insight is appreciated.
It seems like you are doing everything right here so we appreciate your patience during this process of troubleshooting the issue at hand. While I understand that the drivers were updated have seen some instances (example #1 and example #2) where the behavior was resolved by uninstalling the drivers completely. Can you try to uninstall and let me know if you see a change in behavior?
Furthermore, when you update the drivers where did you grab the update from?
