i own a MacBook Pro 2011 which i have loaded with linux.
I am trying to run the flightgear simulator (v.2.4.0 compiled from source) and i am seeing some artifacts that ruin the experience.
I have attached three screenshots that show the problem.
I have to say that sometimes i've managed to load the simulator and it looks great, without problem, but this starts happening, and after that, until reboot i have not managed to see it well again

I really believe this is just bug 39730 in another game.
