I have not heard of this happening on an MMe, only blank screens that require you to turn the car off and on again. Hopefully, it was just a one-time software glitch.
However, I’ve seen similar display errors with laptops. There was a case with 17” MacBook Pros where a defect developed in the circuit board as the GPU heated with use. It caused pin separation that resulted in sporadic patterns like this. Hard resets made it go away for a while.
Keep your eye on this one. If it happens again, report it to your Ford service center immediately.
