I used the DDU driver uninstall and clean reinstallation, and
every single time. I see all that @FlyingNautiker has tried and get the same results as he does. I also had two flawless years with all the good content. I guess the only thing that is needed now is to see if Asobo finds a fix and hope they are working around the clock. I am watching closely the reviews for X-Plane 12. It would be interesting if someone that is having these same issues in MSFS, tries XP-12 to see if the there is a graphics problem or not. If not, then it is an MSFS issue. This is strange because so many of us are having this issue, but I still see most of the YouTube MSFS content creators still publishing some flight including using VATSIM.
