Hi!
I just installed FlightGear 2017.2.1 yesterday. I really want to try it out, but I have a pretty annoying graphics glitch that happens whenever I'm in the loading/startup "splash" screen and in the cockpit. I'm using a vanilla version, with the default Cessna plane without any special weather conditions. I am also just launching at the Boston Airport. Please help me. I am quite new to the Flight Simulation world, and I may not understand some of your terms. I've also already checked the Wiki and I couldn't really find anything related to my problem.

My specs are as follows:
AMD Quadcore FX-4300 3.8 Ghz Processor
AMD Radeon RX470 GPU w/ 4GB of VRAM
Windows 10 Home
8 GB of RAM
1 TB HDD
Thanks!
