Hello,
I am using P3D v4.3.29.25520, GTN 2.06, GTN Trainer 6.21.0. Whenever I try to use GTN in a virtual cockpit my screen keeps flashing but when I click on the pop-up display it gets back to normal. I can normally click and it functions as it should be but the screen.
It's not a problem related to the aircraft because I've tried with Carenado, RealAir, FlySimWare and I always get the same error. Tried to do a fresh install and the exclusions mentioned in a few pages behind, none of this has worked.
