I spent nearly 2 days loading MFS 2020 from DVD plus all the updates. Some aircraft panels are displayed as a check pattern. In cockpit view on the Cessna 152 some of the instruments and all the window views are also displayed as a check pattern. I don't really want to install again from scratch - is there some way of debugging this? I have a high spec PC running Windows 11, and the graphics set to the lowest option.
