For X-Plane users with an AMD graphics card on Windows or Linux: there appears to be a bug in the 13.11 drivers* that cause corruption in HDR mode; the symptoms are square artifacts of missing clouds and missing windshield in aircraft.
If you can run the 13.9 drivers, stick with those; if you have one of the new Rx 290 cards and you must use newer drivers, turn HDR off for now.
These bugs are Win/Lin only – the Mac AMD drivers don’t have this problem.
Yes, I've used AMD Issue Reporting Form.
