Service told me to do a soft reboot with the scroll wheels each time it occurs and wait for a future firmware update to resolve. As a software engineer I am very used to software bugs... After all, I am an expert at creating them
But my wife who is non-tech thinks it is crazy that we spent 60k for a car with the main screen rebooting itself, going off and staying off while driving, screen artifacts, yada yada... Meanwhile service just says this is part of owning a Tesla. I missed that on their sales pitch, doh!
