Thanks for talking this through today Ron, try those things that I mentioned on the phone and let me know if you still see this going forwards. I will send this in to development to take a look and see if they know what is going on. It may be an issue if we cannot recreate the issue.
Check your Display Driver for updates. Check Windows and System Updates for your PC as each release of TBC we likely update our Graphics Engine (Hoops) and that will be looking for all the latest updates from all the Graphics Card providers - so if it worked in earlier versions but not now, it is quite likely that your Graphics Card Driver may need to be updated (or Windows or System Drivers and Updates).
Also try the changes I suggested in Support - Options - Images - try the No Tiling / Do not down size option to see if that helps.
Those other settings in the Support Options Display - Enhance surface visualization in Plan View and Use Double Precision Patches can also make a difference in some cases.
Let me know how you get on.
